I'm saying that large inboxes can be generally bad for MUAs including
mobile and desktop.  Their just downloading and constantly grinding
through data that isn't really being used.  Same thing for the server.

If you have an inbox with 10K emails, are you reading them all?  No, but
you are likely checking the inbox every 5 mins.

And if you have a 20GB INBOX and you download it on mobile, depending on
the MUA and settings, you might be just using a ton of cell data and
storage on your phone.

Dovecot, of course, has intelligent caching and that helps a ton but
overall it's an efficiency thing.  Though not that long ago, it was also
a way of keeping some MUAs like Outlook from crashing when the PST / OST
file got too large.
