(note: these are my observations as a maintainer of a derivative)
Indeed there are still issues, most notablly IMO that firefox-esr's build-dependencies have been unsatisfiable in testing for over 7 months because rust-cbindgen has not been able to migrate to testing.The rust ecosystem in Debian recently had (and I expect still has) trouble to properly migrate to testing
yeah, it is a shame :(
Especially when cbindgen's testsuite is fully green.
I think running autopkgtest for every crates is a bit overkill.
Thanks for spending time to build that list. I would appreciate help to deal with this!
Cheers
