Very interesting. However in my case the private key for email I actually prefer to change it every year, instead of the master key (and seed) for btc, which I would prefer to keep unchanged for many years. I do not trust myself to safely enter/generate/handle any seed on anything other than a Hardware wallet or a piece of paper/metal. IMHO.

makes sense. I thought I ready somewhere that you can generate new keys from a master PGP key.
If only it were possible to generate a PGP key from a hardware device (such as ledger), using the seed, with a pin code for salt!

Yes, that would be nice. My HW generate a GPG privkey and then I just enter that to generate a GPG pubkey in my PC. Then after x time I just generate another GPG privkey from my HW and so on. The only issue I would worry is the possibility of an attacker to get a few of those privkeys and deduct or infere other possible privkeys, like with the HD keys derivation scheme.
