Do innocuous changes like those which you have reverted actually need to be discussed beforehand? I don't see how changing frivolous bits of road (I'm talking less than a quarter mile long each) to fix highway connectivity or indicate that a very short highway segment does not meet OSM's motorway standards requires community consensus. Nothing would get done anywhere else if that were the case. I understand immediately reverting massive undiscussed changes, like if I were to reclassify a trunk route to primary despite it being documented on the OSM Wiki that such a road should be primary, or a particular road which has had its classification discussed before—things like that, but I don't believe that this territorial approach of monitoring each and every minor roadway edit in the state you live in is pro-community. You don't seem to give a true reason for reverting these edits aside from them being "undiscussed", when the vast majority of edits anywhere on OSM are undiscussed by default, or show me which exact venue I'd need to go to (Slack? Forum? Wiki?) in the event I were to discuss any sort of edits with the community.
