We've generally been more conservative with compiler-rt.builtins compared with other parts of compiler-rt, like  sanitizers.  People do ship static libraries to other people, and we don't want them to silently break.

Even if you still consider the ABI "beta", it's not clear to me how we expect users to know; is the "beta" status mentioned anywhere in LLVM/clang documentation?
