I am definitely in favor of this if it is ok with Tanya.

I hope to spend some time in the next few weeks on tracking down
miscompiles, and it would be great to get Clang to the
"early-but-usable-beta" stage so it makes sense to roll binaries for

Tanya, I can also do the x86-32-pc-linux release testing if no one
else steps up.
