I can't help but think that "what's the harm" and similar such responses here are fallacious arguments. This line of thinking just shuts down a lot of tagging-related conversations and disregards any nuance or otherwise about such tags. It shouldn't be so selectively applied because you know, it doesn't actually bring any sensible defense for keeping these tags. Responses that consist of only "why not" are just seriously unhelpful.
I was going to submit a BUR to nuke all of them but I feel that wouldn't be very helpful either so I wanted to wait to see what my (or someone else's) next move would be and if there were other angles to consider either for keeping or removing (some) of them. I do agree with keeping the font tags for more notable fonts after reading through two discussion spaces to an extent. I just don't think any of these newer unknown fonts are useful. It's undeniably tag padding.
Fonts seem like one of those tags where a small subset of established notable tags exist and then a builder looks at that and says "I want more of that" and then creates a bunch of tags out of nowhere for padding. I can't help but think this is what leads to a lot of other categories of tags becoming either accepted or completely nuked out. It starts with one small thing and then gets out of hand.
