Many LN features are ignored by users.
Another example of underrated feature is 0-conf channels (I posted about here) and AMP invouces. Also many still don't know how to use MPP.

What buffels me more is that many still don't know that private channels exist!

I didn't make a guude mentioning blinded paths because is still new and mostly depended on how LN implementations added first to be available in wallets.

I've test it quite a lot, with public and private nodes (I run both), it works nice indeed. The only thing to take in condideration:

• not all nodes are supporting it, so if you encounter one in the path it could fail.
• your LN graph must be well synced and updated. So for a private node that is not always online it depends a lot of the graph to find the right path.
• don't try it with new channels. Use channels that have some history of payments.
