There is a difference between having and requiring it :/ Our current
minimum compiler version is gcc-8 or clang-15 (IIRC).

On the bright side, I think we can be more aggressively with compiler
versions for debug builds vs regular builds. Not being able to build a
KASAN/UBSAN/whateverSAN kernel isn't too big of a problem (IMO).
