That is simply a myth. Adding any feature, even if it can be turned off and mostly ignored, does not mean it's free, harmless or "invisible" to users who don't want it.

Every minute spent on adding priorities is a minute lost fixing or developing some other more important or more appropriate feature. And, at least in my mind, there are many things I'd much rather see than support for priorities.

The risks are significant: increased design/engineering cost, increased complexity, straying from canonical GTD, pollution of the UI, etc. And the benefits are negligible.
