I don’t think it’s fair to say that casual records are not valued or are viewed pejoratively by staff. While some have expressed their own opinions about what types of observations they personally prefer to focus their own ID’ing efforts on, I’ve never read anything from staff that would imply that these are frowned upon or discouraged.
The very fact that the casual status exists shows that they’re valued. If they weren’t valued at all, they’d simply encourage you to delete them or not upload them at all.
And staff have explored ways to not send non-wild observations to the “doesn’t need ID” pile. See:
https://forum.inaturalist.org/t/make-captive-cultivated-not-automatically-no-id-needed/112 (note this has not been marked as declined, and staff have linked to it in other threads)
As someone with experience in project management, I can tell you that something not having been implemented yet is not an indication of low value. Sometimes other things are just more valuable or much easier to implement.
