Apparently, yes.

I found the solution:

SSTATE_EXCLUDEDEPS_SYSROOT = "\
     rpm-sequoia-native->.* \
"

I have added this to my repo's layer.conf.

It may be useful for including in oe-core, or maybe not.

Only recipes depending on older clangNN versions in my
meta-clang-revival trigger the problem.
