It'll fly technically; is the "won't fly" concern that it may not be
obvious to the user that an MTP3 option is the way to control the
behavior of other protocols?

If so, another option might be to use "prefs_register_module()" to
create a preferences module with a name that's *not* the name of a
particular protocol, register preferences under that, and make the
variables controlled by those preferences global.
