I had a similar thought, but wouldn't the existing uploadpackfilter
config take care of this?

I guess the catch-all "allow" option defaults to "true", so we'd support
any new filters that are added. Which seems like a poor choice in
general, but flipping it would mean that servers have to update their
config.

I do wonder if it's that bad for clients to be able to specify something
like this, though. Even though there's not that much use for it with a
regular partial clone, it could conceivably used for some special cases.
I do think it would be more useful if you could OR together multiple
types. Asking for "commits|tags|trees" is really the same as the already
useful "blob:none". And "commits|tags" is the same as tree:depth=0.
