Sure. But selfhost (incl. stuff like selfhost w/ sanitizers) is a fairly
important special case we may be able to agree on. (and I say this as
somebody that largely builds cross-compilers (targeting PS4))

In that case, RT wouldn't "have" to be core. We use GCC rt-libs on
GNU
systems, even for self-hosting.

Even if we move to full RT builtins (which I really want), we'd have
to get rid of everything else in that repo to move it to core.

cheers,

I think there is a compelling argument for selfhosting with sanitizers (the
sanitizer bootstrap bot has saved me more times than I care to admit).
