These are all good arguments for enabling HTTPS and making it the
default (which I've said repeatedly is a move that I support, or at the
very least don't oppose), but not for *disabling* the possibility of
plain HTTP.

"There might be a reason why a user would want to use encryption" does
not negate "there might be a reason why a user would *not* want to use
encryption". I'm claiming the reasons as in the latter exist; one (and
not the least) of which is that downloading files off people.debian.org
from d-i preseeding happens today, is a valid use of that service, and
cannot be done if HTTP is disabled. If you think there aren't such valid
reasons, you either need to show me why my claim is wrong, or why the
costs to doing so outweigh the benefits. So far I haven't seen anyone do
