By the same token then, we probably shouldn't be suppressing the warnings at the top of certain files; the effect would be the same (but limited to only those files that /do/ test deprecated features).

Hmm, what about making this controllable via a command line option to regrtest? Then what should the default be? Probably, "don't suppress" and then most people will just have to ignore the warnings. In that case, I'd argue that the switch should be "suppress" by default in the final releases, so as not to confuse end users.
