for a start \exp_after:wN should normally not be needed except on very
low-level programming (which should largely only happen in the kernel). For
the rest the l3expan concept really provides a much more powerful and
consistent interface.

I know that for 2e programmers that is a bit of a getting used to as we all
used \expandafter in the past all over the place, but in reality it isn't
needed usually.

So providing yet another name for it isn't something I like to see without
compelling reasons and I'm not sure there is one (but perhaps 'm mistaken).

If we would add it then I guess the right name wouldn't be
\exp_arg_unbraced:No - it would fit more into the group of functions called
\exp_last_unbraced:N... but as I said I'm not really sure that adding that
would help, would it?
