Though I'll add a comment to convert_bpf_extensions() that build_bug_on

My concern would be that in case the code gets changed, this spot
could easily be overlooked by someone possibly unfamiliar with the

So I guess it wouldn't hurt or cost us much to also adding the
BUILD_BUG_ON()s there instead of a comment.
