This value no longer seems to be in use.  Maybe it should be removed.

Several of the values are unused now. I can remove them (in fact, I have
prepared a CL to mark them as deprecated in histograms.xml) but I would need to
insert placeholders to keep UMA data consistent.

That still seems preferable.  OK to do it separately if you want.
