Sigh.  Again: my point is that one way is verifiable and debuggable, the
other is not.  If all that's stated is "7.0.0", and a user's result is
different, there is no way for the user to know if it's because Unicode
released two different files under that version number, there was an
error in the download, something changed or went wrong in the LaTeX
processing code, or ... who knows what.

With a factual, verifiable, piece of information about the input files
used, any problem can be easily diagnosed, instead of having to be
guessed at.

(Not that it's likely to matter in practice, I grant you.)
