I'm pretty sure other projects have been in simlar places to llvm (in the past, was seeing version-based releases of the Gnu-compiler chain in the gcc4.x range, while new releases from the vendor were maybe @ gcc7.x or more). Not the only example that I think there has been over the history of a rolling rel. vs. a version-based release like SLE & Leap.
With the difference that SUSE is massively involved in GCC development. Not so much with LLVM, and when it comes to me I'm not sure if I'm willing or able to debug issues in LLVM 7 (version 12 came out a few days ago). With a newer version I can at least see if trunk has it fixed and then try a backport, or file a bug, but with an old version that can get difficult.
