I would have been interested a few months ago but since I am going to
start a new job next Tuesday.
I don't think that would be reasonable.

That is starting to be important.
If you change the ABI, we, distribution, would have to rebuild all
packages depending on
LLVM & Clang. If we keep the same ABI, this work won't be necessary.
Changing an ABI is really a nightmare from the distribution point of view...

libLLVM-3.4.so should be OK if the ABI does not change.

I am not sure that it is about date but more about the number of
critical bugs in the current stable release...
I would add a 10) point.
Clearly document what kind of patches are acceptable from a stable release.
For me, it should be only important bug fixes, no new feature.
