There's another downside that's IMO bigger (and not addressed by an e.g.
API-based solution, or even Github offering this feature).

When multiple projects share a repository, partitioned by tags, then the
"file bug", "browse bugs", "search bugs" actions are too far apart in the
Instead of X home -> browse bugs -> file bug, the path becomes LLVM home ->
browse bugs -> browse X bugs -> file bug -> file X bug.
It takes longer, there are more chances to get lost and confused.

(This is assumes there's little overlap between projects in terms of bugs,
which may not be true for e.g. llvm-backend <-> clang, certainly is true
for clangd, other projects are probably debatable)
