I personally trust the judgement of the moderators, and would not want to prevent them from having some preliminary stage-setting discussions with other parties in private if they felt that that was appropriate. Obviously any actual change in policy will need to be discussed openly here.
Anecdotally, it seems that there is a substantial class of potentially valuable contributors who feel that the basic framework of MathOverflow is unwelcoming. Whether or not you agree with that, it seems suboptimal to force them to use the same framework for even the earliest stages of a discussion of their concerns.
[UPDATE] Let me amplify my thinking a little. I am guessing that the mooted discussions mostly arise from concerns about gender balance. It is undeniable that among users of MathOverflow, there are only a tiny minority who are women using their real names. There may be a few more pseudonymous women, but nonetheless it is clear that the proportion of women on MathOverflow is far below the proportion of women in academic mathematics. I find this disappointing; there are certainly very many women whose expertise and insight would be extremely valuable if they chose to participate. I have not seen an explanation of this phenomenon that seems compatible with easily obtainable data.
Of course, we should consider explanations like "women do not regard MO as a productive use of their time, and they are correct in this judgement". While this should not be rejected out of hand, it would be strange to have a huge gender imbalance in judgements about the value of MO activity, and this would itself seem to need explanation. Often I see people suggesting that women are unwilling to participate in some kind of forum because they suspect that they will be harassed, or their qualifications belittled and their opinions ignored. I have tried to search for instances of this sort of thing on MO, and have found very few. In cases where women do participate using their real names, it seems to me that interactions are very normal, with other users being respectful and appreciative to experts, and helpful to novices. Certainly I see MO as being much more friendly to women than Twitter, despite the fact that women are far more common there.
This situation seems quite mysterious to me. I think that it is valuable to seek insight and suggestions from as many places as possible, even if the community ultimately decides not to accept such suggestions. So if there is some group who may have useful ideas who are reaching out to the moderators, then I think that the moderators should be as receptive as possible without committing the community to any course of action. Because I think that the situation is mysterious, I think we should avoid making assumptions about what kind of insights and suggestions we might receive.
