Is there a place to discuss specific suggestions?
For example, I'm not sure about the 'ams -> amsmath' suggestion. The AMS has more packages than just 'amsmath', in particular they have their 'amsref' stuff. I would regard the 'ams' tag as ambiguous, and so not as one that is synonymous with another tag. Rather, whenever 'ams' rears its ugly head, it should be retagged to an appropriate tag.
To expand on that, synonymous tags should really be synonymous. I think that the most obvious examples being singular to plural, or no-hyphens to hyphens. Where a tag is ambiguous or just plain useless, the questions should be retagged and the tag effectively dropped.
