> The problem with that is it breaks end to end encryption. Depending on how it's implemented, I'm sure there are security issues to consider, but I'm not following how this kind of feature would necessarily cause a breaking encryption problem.

Given that modern HDs in most professional machines are in the 1TB and way up range, I'd say that anybody who wants to use the full power of email would probably consider that tradeoff worthwhile.
