We have always attempted to allow world and kernel to build with a slightly older compiler, in particular at least for the period immediately following a tool chain update. We'd like to avoid having downstream projects or others with slightly atypical build configurations avoid surprise breakage. For example, Cirrus-CI runs use a toolchain package to reduce the build time, and it is now failing: https://cirrus-ci.com/github/freebsd/freebsd-src/main. This is easily fixed by bumping the toolchain package version of course, but it is much better if we can avoid this altogether.
