As I read Julian's proposal, that is precisely what he's suggesting,
pushing this into the server. And it seems like a quite reasonable
idea, too, though probably not free, as you point out. You would need
to hold not just a single directory at a time, but all the directories
along the current path. Right?

But how bad is that? Seems to me like producing sorted status would be
a good thing in at least two dimensions, user experience and regression
testing. Shouldn't we be having a cost-benefit discussion, rather than
an unthink-that-thought discussion?
