Morning,

Yes, in general, Bitcoin does not do anything to prevent users from
discarding their keys.

I don't think this will be fixed anytime soon.

There are some protocols where, though, knowing that a key was once known
to the recipients may make it legally valid to inflict a punitive measure
(e.g., via HTLC), whereas if the key was never known that might be a breach
of contract for the payment provider.

Best,

Jeremy
