This revision is now accepted and ready to land.
This looks good to me, but I'd recommend waiting a bit before landing in case there's further input, as this is a non-trivial API change.
I think separating AttrBuilder (which stores attribute keys and values) from AttributeMask (which only stores keys) makes sense conceptually. With the current API, it's not really obvious that the attribute values are completely ignored for removal operations -- on the surface it looks like the attribute would only get removed if both key and value match, but that's not how it actually works.
This should also give more flexibility in optimizing AttrBuilder for it's primary use case (which is adding attributes).
