I agree, it can be outside oe-core and enabled + maintained by those who
care about it, it doesn't need to burden you Khem when you're doing all
glibc upgrades in oe-core.

I agree, it looks like more reasonable replacement for uclibc.

I agree again, few people are using it (based on recent survey from
Cliff), so having it in separate layer looks good to me.

I won't ever use poky-tiny, but switching it from glibc+kconfig to musl
would probably make it easier to do some build testing on Yocto AB, so
in the end it should improve test-coverage than current uclibc in
oe-core has.
