I have been monitoring too ;)

No plan for this.
I haven't hear about anyone on this.

llvm-openmp has a pretty (very?) stable ABI/API. I am not really worried about the compatibility
with more recent versions.

However, it is unlikely that Buster will ship with llvm 4.0 as LLVM has 2 releases per year.

I don't have an opinion on this!
