Hey, I completely agree with @rijndael comment here. BIP39 specifically focuses on mnemonic words, while the concepts of derivation paths is original proposed in BIP32 and then BIP43, BIP44, BIP49 and BIP84, which is actually build upon BIP32 to provide additional specifications for accounts and addressing schemes.
Also you specified about wallet descriptors and this particular statement:
I think the statement that suggesting that they will take over seed phrases is inaccurate and false. Wallet descriptors address the issue of derivation paths when generating addresses, especially when users switch between different wallets. Like the mnemonic words alone is not sufficient for wallet recovery; you also need to know the derivation path used by your previous wallet to generate addresses.
For example, if your previous wallet generated addresses based on BIP44 (P2PKH derivation path: m/44'), you need to know that information during wallet recovery. If your new wallet generates addresses based on BIP84 (P2WPKH derivation path: m/84'), both wallets are incompatible, and you won't retrieve the correct wallet information, such as balance and transaction history. That's the reason the website you mentioned https://walletsrecovery.org/ exist to sepcify the supported paths by different wallets.
Wallet descriptors provide a general syntax to address this problem, using constructs like pk(), pkh(), wpkh(), and so on, to specify different derivation paths and scripts. However, it's important to note that wallet descriptors are not intended to replace seed phrases but rather enhance the management of wallet structures and derivation paths.
Also BIP 39 is actually a well-established standard that defines how mnemonic seed phrases are generated and used for wallet backups. It has gone through a proper review process and is widely adopted, like BIP39, BIP32, BIP43, BIP44, BIP84 these are considered as industry standard nowadays for developing bitcoin wallets.
You agree with rijndael because you think there's a disagreement. I don't disagree with what they said. What they described is how it is used.
BIP39 is actually just for the mnemonic words
Which I simply say is exactly the problem with BIP-39
Hierarchical Deterministic wallets and derivation paths (as a general mechanism) are from BIP32.
Which is irrelevant to the fact that BIP-39 encoding doesn't include the derivation paths which makes it a half assed piece of patch work.
BIP 39 itself under motivation says:
"This seed can be later used to generate deterministic wallets using BIP-0032 or similar methods."
But it can't be used to generate a BIP-0032 wallet, because of all the missing information, hence the wallets recovery site, hence BIP-39 is a half assed piece of patch work.
Patch work, as in an amalgamation of incomplete parts.
It has gone through a proper review process
and was nacked to the point of earning this label:
"Comments-Summary: Unanimously Discourage for implementation"
Go on, go to the BIP, hit ctrl + f and paste the quote.

and is widely adopted
Which has caused panic and confusion for people switching between wallets, or using a wallet that updated to use a different derivation path.
However, it's important to note that wallet descriptors are not intended to replace seed phrases but rather enhance the management of wallet structures and derivation paths.
I don't think it matters what the intent is, I believe the function of "enhancing the management of wallet structures and derivation paths" will result in seed phrases getting naturally replaced. You already don't have a seed phrase for your lightning backup by the way. Liana wallet seems to assume that instead of backups, you'll just have so many devices with varying levels of accessibility to recover funds. If we decide to implement CTV or other covenants I don't think you'll be able to recover those wallets with BIP-39 either.
Half assed patchwork is workable for most people right now, but the world is changing brother! Get ready for it.
