There should be no reason to have and maintain community-faq as a living tag. Certainly not to continue pasting a boilerplate into questions themselves explaining the tag's usage.
Yes, it spawned out of wanting to create community FAQs, but this is already served by the frequent tabthe frequent tab which is driven by links and references from actual use. Not by decree or one person but by the Super User community.
community-faq is also redundant when you look at all the questions that are on the frequent tabthe frequent tab.
The tag's use is also primarily for those who want to look for a master question to mark duplicates against. As such, it's not useful for new users as a point of referencenew users as a point of reference. A new user would not search for "community-faq" when their problem is about low battery usage. They'd search for "battery" or "batteries".
If we need to track which question(s) best cover or explain whatever problem is out there, then it should be part of the tag wiki.
The virus tag wikivirus tag wiki has been made one of those kinds of examples. A use case designed for such.
It's of the community and of the site and not just a dump explaining what the tag is, but how to best use the tag. And here, one of the best uses of the tag is the drill down over to the master reference list that duplicates might be caught as.
