Apparently the prefix argument does not work, though you can do the same
with a macro.  Maybe adding a "t" to toggle the selection, though this
would be a very specific use-case.

What do you think about extending the package-menu-filter commands with
a way to mark all packages instead of filtering?

There is also M-x package-list-packages-no-fetch.

No, that is not my intention, I just wanted to clarify a point.
