Depends on what you mean by "stable". It should not have more bugs than the 0.1x
branch, though of course bugs may be introduced by any modification in the code.

Concerning foreseeable future compatibility breakages, things are more complicated:
- concerning compat, cctb, loader, regs, I don't plan to do breaking changes
other than required for the possible merge with Heiko's luatex.sty.
- mcb (aka luamcallbacks) and modutils are more likely to change soon, we'll
need to discuss a few points.

Btw, this is the reason why I didn't push everyone to switch to the master
branch earlier: I wanted to minimise the number of times we needed to
synchronize for such changes. Of course, now than TL10 is approaching, it makes
more sense to switch to the latest versions now without waiting any more.

To sum up again: any of master and 0.1x can be a candidate for inclusion in TL,
and it's your choice.

You can do as you want. luatextra still provides a few more things, but if you
don't need them, you can load luatexbase and luaextra directly, but loading
luatextra is not deprecated either.

I agree. Élie's suggestion of lualibs sounds fine to me. (Or luautils, too.)
