Yes, you'll want to add seq-* aliases for things like elt.

We can start by having seq-elt be an alias for elt (rather than the
other way around) so as not to need changing anything else.

I think it's not just an implementation detail but a fundamental
limitation, so I'd just remove it.  Those who really want it can use
subseq (or whatever its new name will be, e.g. seq-subseq).

You might as well put a

   ;;;###autoload (require 'seq)

at that point (or add it to loadup.el).
