Presently there is a flurry of edits, rollbacks, re-edits etc. mostly focussed on tags. Apparently some user seems to think that there are too many of them, or that they are redundant, or something else. I can't say precisely what, since they just delete tags, rather than discussing the matter here.
Might the tag deleter(s?) clarify their intentions? Or might the moderators clarify that tags are fine as they are and, if necessary, protect the questions involved in the changes? Of course any other opinion is welcome!
