How about a global switch like \UseLaTeXeCommands (or whatever)? I tend to think
the current name is already long enough...

Anyway, if Frank's idea of having separate packages xparse-2e and maybe latter
xparse-gellmu or how knows, currently the switch is done by calling

\usepackage{xparse-2e}

or possibly another one (since l3 is still used on top on 2e at the moment), so
I guess the question will only arise latter. Anyway, probably only one on the
possibly various xparse-* will be used at the same time, so I don't see any
problem with them using the smae command name.
