Not exactly, it's more like a history (of email addresses we've bumped into).

It doesn't contain data the user painstakingly created, but deleting it
would cause the suggested completions to be much less useful for a while.

So it's somewhat like a cache, except that a cache is expected to affect
only the performance but not the actual behavior.

Same: it's a history (of files we visited).

Agreed.  I think package.el's `archive-contents` file do qualify as
caches, as do the <pkg>-readme.txt files.
