I was working with a [question](https://meta.stackexchange.com/questions/1777/what-html-tags-are-allowed-on-stack-overflow-server-fault-and-super-user) that was a part of the FAQ, and it wouldn't let me submit the changes because it "must include one of these tags – [bug] [feature-request] [discussion] [support]".

Do all future edits to FAQs also require one of those tags?  This means that you are effectively [limited to *three* tags](https://meta.stackexchange.com/questions/22186/how-do-i-format-my-code-blocks) specific to the question's content, and might have to remove a good tag in order to make room for [support] or [discussion].  Doesn't FAQ already imply [support]?

Can questions already tagged as [faq] (a locked, moderator-only tag) be exempt from  required tags?

Though I of course don't know the backend implementation, if [faq] was added to the list of required tags (and the missing-required-tag error message cleaned up so that non-moderators weren't prompted to use it) while still being a locked tag, then any 2k user editing an FAQ would "meet" the required-tag requirement, without allowing non-moderators to add or remove [faq].
