I don't think so. You and Stefan simply have differing opinions.

This decision is a mistake. Please reconsider.

If I understand you correctly, you are saying we should not support any
feature in clang/LLVM unless we can do the same with gcc, because
although clang/LLVM is free software, it is non-copyleft. At least
that's what I gathered from your other posts in this thread.

But by the same reasoning you are applying to clang/LLVM, Emacs' must
not support any feature from Subversion (which is Apache-licensed)
unless the same feature is present in git, hg, or bzr, or we must
implement it there first. Likewise, we must not support any feature in
CMake (which is a BSD-licensed build tool), unless the same feature is
present in GNU Make, or we must first implement it there as well.

Is that correct? Because if so, you are drawing the line now between
copyleft and non-copyleft, whereas it used to be between free and
non-free.
