You're right, of course. I definitely should not have included the
caching as part of the core proposal. As Jim mentions, since this
feature would only ever be useful when online, the caching may not even
be necessary at all.

The reason I did mention it, rather than just append "Inherited
properties would make this faster", was that this feature would require
something that I've never seen in an inherited properties proposal
before; we need to know where the property is inherited from, not just
its value.

In fact, in my original proposal, we didn't even care about the value,
just where it was set. I do, however, like Jim's suggestion to put a
sub-path in the treeroot value to handle partial-tree branches.
