I agree that it's reasonably rare (though anecdotally I do feel like I'm running into it more often). It's correct that I'm essentially arguing against requiring "invasive" support libraries that change the nature of ruby (admittedly, that's subjective) in gems. Gem authors should consider their dependencies on the basis of necessity, not convenience. Keep the scope low and compatibility high.
