Thank you so much for your work!  Especially on Bug 1157850, that has
been annoying me for quite a while.

Most of our work has been on the Rust integration side, and also PowerPC
(I believe mhoye added PowerPC to Tier 3 specifically because of the
combined efforts of us and Fedora.)

It would probably be best to tried and add musl as an "and" to the Tier
3 statement about the various architectures.  This way it isn't specific
to any one architecture nor maintainer, but rather a community effort
from all interested people (you, us, Void, Alpine..)

Best to you and yours,
