Anyone can certainly remove the tag, but I don't think it's a good idea that such a tag be removed without the release team's approval. I see these tags as being for the release team's use; hence the team should determine by itself whether these tags should be applied. Maybe the tags should also be moved from the main namespace to the release team's "usertags".In other words, if a tag indicates a special case, that special case should be justified with a specific explanation. I would like to see such justification expected for every such tag, enforced by the convention that tags with *no* justification provided can be summarily removed by anyone. This would place the burden of argument in the correct place, as I see it, while not needing anything as heavy-handed as a policy requirement. Is that feasible? Is it reasonable?
