To get an enumeration of available objects, don't you need to use only
"blob:none"? Combining filters (once that's implemented) will get all
objects only up to a certain depth.

Combining "tree:<n>" and "blob:none" would allow us to reduce the number
of trees transmitted, but I would imagine that the savings would be
significant only for very large repositories. Do you have a specific use
case in mind that isn't solved by "blob:none"?
