Does this mean you're OK with the prompts otherwise?

I think if the user asks to install an older version and forces
package.el to do it, they should be responsible for any breakage.

The prompt is too long already so I don't want to extend it with "...and
this will break installed packages if they depend on the newer
version."  But maybe package.el could show "broken" packages that can't
be activated because of the version mismatch?  Or is that already covered?
