I have the impression, and I absolutely don't spend enough time there or have enough insight into someone just from their forum posts to be in any way sure of this, that at least some CharOp posters have agendas that they are very attached to. I'm not saying that this biases them or anything, but a lot of 4e players have some very, very dogmatic ideas about what 4e is supposed to be and/or should be.
I think that a hazard WotC faces in asking CharOp for help is that (IMO) they can't and shouldn't cater to those agendas (especially where they are in conflict, of course). One of the things that I've seen throughout the life of D&D is that D&D doesn't really specifically and implicitly tell you how to play the game (in the way that some other games do). That's up to the individual group to decide / figure out. A lot of what CharOp does seems to be contingent on a specific way of looking at D&D, and a lot of the questions I've seen there seem to be of the sort that are only going to be satisfactorily resolved by knowing "why" WotC designs stuff the way it does - and I think that not putting that out there in many cases is not just a matter of lack of resources, but a part of the way that D&D works.
This has caused some issues over the years, but for me at least it's part of why I play D&D over some other games. Obviously with the advent of online communities such as ENWorld we've moved closer to a consensus, yet the lack of specific official answers has kept things mostly up to the individuals. And I'm not sure that WotC is going to be able to give CharOp what CharOp seems (to me) to want without coming out and being much more upfront about "this is the right way to play D&D".
Is it reasonable to think that WotC might be stepping in a hornets' nest here, liable to suffer backlash from asking CharOp what it thinks and then quite possibly not following through on that information in the way that the CharOp posters might like? Or (hopefully) am I just being a bit paranoid?
