If a support question is asking for something that the Stack Exchange team needs to do, and will result in either status-declined or status-completed then that question had better be a bug report.
If it was not a bug report about fixing something which was clearly broken, then it was more than likely a feature-request and was tagged incorrectly.
Responses will be in the form of reaction to the request in the case of an incorrect tag (which is probable and happens often). These are not discussion topics per se, but they are views which are available to be vetted by the community through voting in addition to votes on the post.
I see this situation as desirable, because when a user posts an answer in reference to a request (or even a bug report) it is able to be vetted by the community through voting as opposed to the more one sided and transient version of responses in comments.
As for "honoring" tags, I see moderators and consistent contributors answer support questions all the time. While it may not be obvious on MSE, there are moderators from other exchanges who post answers here (for example Brad Larson) as well.
