I honestly wouldn’t consider the faint path through grass one as "good’ in a meaningful sense of the word either. Good is essentially an intermediate value and intermediate is the beginning of bad which continues on for three more vague values.
It’s not a useful key without wording changes, but wording changes will make it (temporarily) more broken than it already is which will probably deter changes passing. I do generally agree with more photo examples being good but I’m not sure the key will really benefit from it and realistically speaking having proper photos would probably break historical usage.
I’ve soft proposed a new visibility key based on discussions and looking at different formal systems that should be more grounded in non-alpine specific reality and verifiable. Ideally this or something like it would slowly take over and then trail_visibility be used as a fallback.
