+1. I think I just wanted to excuse my confusion...

Cleaning parts of the tree isn't supported as far as I know (not that I've
needed it). You can build parts of the tree by specifying the target
(e.g. ninja src/backend/postgres) or by specifying meta-targets (e.g. ninja
contrib backend). I've thought about contributing a patch to meson to
automatically generate targets for each directory that has sub-targets - it's
just a few lines.
