We do this so we naturally get an implementation for lists of things that do HashInto. It's hard to arrange otherwise.
To allow for using faster multi-exp algorithms now used in backend.
Nobody actually needs this!

There was a problem hiding this comment.
Any rationale on why you go this way (by value instead ref?)
There was a problem hiding this comment.
XOnly is Copy so I think it's conventional to not return references to Copy things. On top of that There's no reason to leak the implementation that keyPair stores an XOnly (it could store a Point<EvenY> instead).
(that comment needs to change though).
And add a way to clear them manually to try and discourage serializing nonces.
