Don't we just use the working tree .gitattributes by default, and ignore
what's in the endpoints? In a bare repo we wouldn't have that, but I
think the recently added attr.tree and --attr-source options would work
there.

You can't use attributes from multiple trees in a single request, but I
doubt that would be a big drawback.
