is there an actual reason that inserts can't start working down from
64k?

etex.sty can't do this, because the basic set of inserts has been
allocated by the time it gets to run, and that plainly isn't a
constraint on latex 3.  but does it matter for expl3?

(i have once spent time on thinking this issue through, but i'm not well
-- still -- and can't remember what conclusion i came to.)
