I don't think that is entirely true. It depends on the magnitude, but
people often use "this takes XXX MB" as a benchmark.

I realize in some senses it is only meant as a view into how performance
should end up, but it *is* used as a direct measurement on its own.

And personally, I wouldn't mind being a bit more compact. It isn't a
huge deal, but when I'm testing conversions, etc, I often have to have
multiple copies of a large project.

Anyway, it certainly isn't the highest priority, but I do think it is a
common measurement (if only because it is easy to do).
