Well, actually, a lot of work has recently been _finished_, so
glibc/binutils/kernel/... now have stable support. Early adopters have
been using it for a year or few.
The adoption has been rather minimal as far as I can tell; what I meant to
ask was more if any current/potential users of musl intend to use it if
possible. In other words, if you or someone you are in commmunication with
is going to start using musl x32 for any reason besides "It happens to be
supported".

There are several other articles you can find, if you look up john the
ripper gpu hash bcrypt (or anything reasonably similar...)

1. Is busybox the only login we want to support?
2. Is login (or similar) the only place crypt is used?
3. Do we want to rely on the busybox internal code?
4. This is "If you plan to add hashes (which Rich has stated
that he hopes to do, in the original post), please consider
making bcrypt one of them."
