[aur-general] Are AUR VCS packages that depend on AUR VCS packages from other projects a good idea and who should decide on that ?

They came for mesa-git, did not took care about which dependency were
pulled. They update mesa-git, but don’t think of llvm-git because they
were never informed this is especially relevant for mesa-git.

Other case : user already has llvm-git for whatever reason, but like you
said don’t update it (they forgot about it, don’t care…). They install
mesa-git from AUR, llvm-git dependency is already satisfied. But at that
point, their llvm-git could even be older than repo llvm (granted, at
this stage they would have other issues). So depending on llvm-git in
mesa-git does not achieve a lot.
