Hi AdamISZ/waxwing,

I discussed with the maintainers, and we do consider MuSig2 and adaptor
signatures to be in-scope. However, we don't currently plan to proactively add
these features ourselves.

The reason the library currently contains an implementation of BIP 340 and not
only raw elliptic curve operations is that we use BIP 340 in the ChillDKG
reference code. So if there is demand to specify a scheme that is based on
MuSig2 or adaptor signatures, then a similar reasoning would apply. MuSig2 would
be particularly easy to add because it already has a python reference
implementation and test vectors.
