That's exactly my point. If sponsoring options is done by the community, and is relatively easy, then fewer proposed options in one category does suggest that this category is unpopular with the community.

If there are several variations of anti-RMS proposals, it suggests that enough people care about the specifics of how the rebuke is worded, etc., but that generally there is enthusiasm about an anti-RMS stance.

If there are fewer pro-RMS proposals, then either they were proposed by people who don't support that option, but are putting it forward because they think it should exist as an option (as you suggest), or because there are fewer people who are enthusiastic enough to care about the minutia of how a support message is to be worded. Either way, that seems to me like less enthusiasm around an anti-RMS proposal.
