Would be nice to have a better understanding of why they have been added.

Performances, bug, stability, etc.

Besides the arm issue, what otherwise is blocking you with the current 
llvm-toolchain-6 ?

Do you know if there is a documentation somewhere?

Sure but it doesn't scale and this is against the Debian policy (cf 4.13).

We have already too many versions of llvm in the archive, no need to add 
one more (esp
as I am active on llvm-toolchain-*)
