On the contrary, the simple user nowdays doesn't care about
file sizes and disk space, but does care about attaching a
dozen files to an email vs. attaching one archive.

(The ideal fix for that use case would be to support attaching
whole directories. They can be transparently converted to an
archive when you attach them and exploded to a directory
when you save an attachment. But this won't be ubuquitous
any time soon, so we still need an easy way to explicitly handle
archives.)

Anyway, I agree with your analysis of "Compress..." being best.
