I haven't looked into it, but if the tomlkit API really is compatible,
the first suggestion sounds good to me.  It would be good to notify
upstream about the unreasonable "pinning" in that case.

Otherwise the second suggestion sounds good too.  There is plenty of
precedence for both solutions in Guix and is really something that needs
to be decided on a case-by-case basis.

Thanks for finding and following up on the issue!  :-)
