Would it be worth retagging questions which are making synonym requests as synonym-request. From what I see here, it sounds like the mods could perform this sort of soft-tagging without bumping everything -- sorry didn't realize that this would bump questions and stopped when I noticed after the fourth question.
There are a whole bunch of questions which could be retagged, if this is deemed reasonable. Note - for those interested that I did not propose the synonym-request.
