Yes, in general, transitions between systems are vulnerable points in
a process. Some of us, I suppose, manage this vulnerability by trying
to preserve what we already think we have in our pockets; others of us
do so by reaching out to what new things we might acquire.

I don't know of a principled way to finesse this problem. I think the
usability argument trumps others, but it's not a slam dunk, itself,
and can be seen in several ways.

Hence, my actual position is to allow both "$" and "?", though not
mixed in one query, and stop worrying about "needless complexity". Or,
rather, worry about it in more tractable ways.
