It's also much more efficient, at least with our current implementation,
as we do not have to worry about matching this entry when we are dealing
with /some/other/path. See [1] for a pathological case.

I see "with our current implementation" because I could imagine a world
in which we have a more trie-like structure for non-wildcard patterns.
But I don't think anybody is working on such a thing.
