Maybe take it from the other point of view: the *only* problem with excessive fancruft is that it damages our credibility.
I don't believe we should compromise our acceptance of content because we worry that some will think less of us. It is not our aim to perfectly match the role of the traditional encyclopedia. We are going to include some content that some think is below them (or should not be in an encyclopedia), that's fine and it isn't our problem. If a user doesn't wish to read about [[Bulbasaur]] then they should take my lead and avoid it.
