Comment 10 for bug 1465709

Re #9, this is what I was referring to in #6: some of the terminology seems to suggest that arbitrary components can be versioned, but I believe that there is, at most, only a fragment of the relevant logic available.

I'm not excited about the code proliferation that would be required to extend this to arbitrary components, especially absent any pull from the user community or even a plausible rationale.

I'm ok with either AESTHETIC-VERSION or VERSION-DISPLAY-STRING.

And Fare (#7) is quite right: the MIN-MAX is a half-open interval [MIN,MAX), where the version must be >= MIN and < MAX.
