Option 1) may seem easy in the short term, but it gets messed up so
easily. We also have a policy to not have any moving-target packages in
the same way, so I'm even less inclined to accept it for a libc.
Same issue with 3).
Integrating a uclibc fork like -ng is probably also a waste of time.

Did you see any real improvements with the snapshot that you used in
your patch?

FWIW, I consider uClibc a dead end for OpenWrt. After the CC release is
done, I want to push for switching to musl by default and fix the
remaining issues with that.
Unlike uclibc, musl has decent code and an active maintainer and
developer community.
Unlike glibc, musl is quite small - actually comparable in size to uClibc.

In terms of performance, I expect musl to beat both glibc and uClibc.
