Spoiler: it’s rejected, but I’m not sure to get why…

Looks like they initially accepted it on the basis that there were reports that the Mozilla build with clang turned in Benchmark results 10-20% faster than the fedora build.

However it was later proven that the difference was not so great and that what difference there was existed because the Mozilla build did not have the security hardening features (which clang did not support) gained from using GCC. So the original decision was overturned.
