This is an active choice.
No packages in kinetic+ use gcc-11.
gcc-11 in kinetic+ exists to apply and test fixes for SRUs to jammy where
it is the default compiler; as well as to compile EFI code that is copied
back (grub2-unsigned).

Furthermore this fix insofar affects kernel compiled kernel, thus yes this
is fixing kernel compiler codepath in jammy only, as kinetic+ is fixed
(specifically kinetic+ kernels require gcc-12 due to kconfig hardening
choices).
