All those names sound like something that a triager can quite quickly remove from an issue after a cursory look. So you clearly have in mind a label for triagers, while the “valid” label is primarily for experts to use (we don’t expect triagers to be able to make that decision). There really isn’t much overlap between these two labels. They mean different things and they will be applied by different people.
I created an issue for the “valid” label on the core-workflow tracker. How about you create another issue for the triagers’ label, and then they can be discussed on separate threads, which will hopefully reduce the confusion.
