I think also, like you don't need a mature filter for every type of mental health condition, which is what is bothering people here. Basically I think the need for a "Mental Health" filter is kind of rare.
If you have a comic with like...someone going through a depression because of a breakup...or anxiety, that doesn't need to be under a mature filter, youknow? Not unless it actually steps into violence, suicide and self harm, which is separate filters.
Personally I write CW or TW for things as simple as...if I have guns or something in my story, so I'm on the side of trigger warnings for anyone that is sensitive to that. But a mature filter is different. When the mature filter can potentially remove a comic from the app, that's a problem, and "Mental Health" is too vague in a sea of comics that are largely about mental health.
