I expect that this should be supported in tree_entry_interesting() at
some point, though I didn't have any immediate plans to do that yet.
One reason for that is I just haven't thought through all the cases to
make it performant (as you've pointed out).  So for now it'll probably
be appended to the backlog (yours, mine, or both) and if there ends up
being a larger demand for it then we can increase the priority for it.
