What is the point of all the hash conversion methods in `ToPublicKey`

[tcharding]

Currently all implementors of ToPublicKey just return the hash argument, what is the point of these trait methods, what am I missing? Is this trait used differently by some other consumer of rust-miniscript?

Yes. The point of these is to convert from an abstract hash value to a concrete one that can be embedded in a script.

Any implementer of ToPublicKey that is not working with literal hash values will need to do a nontrivial conversion.

I'm going to close this. Seems like it's "asked and answered".
