That does make some sense.  We do need to think carefully about these
terms if we change them.  "Upgrade" sounds pretty good for what it does.
 I wonder if "Replace" might be a better term instead of "Revert" for
the other operation.  "Revert" implies to me that you're going back to a
previous version, which is not necessarily true.  "Replace" can mean an
older or newer or just different version.  But "replace" makes it pretty
clear, I think, that you may be losing any local changes you may have
made to the package... it's not too benign sounding.
