I wouldn't.  Part of the reason I mentioned (a) is that write is
writing to a tty, whereas environments are attached to processes; there
may well be 0, or >1, processes associated with the tty, for whatever
value of "associated" you end up using.  (Arguably, write should write
to a user, not a tty, with the historical behaviour of choosing a tty
to write to being a historical accident.  If you go with this point of
view, it makes things even worse.)
