it is not that. i mostly mean that for anything functional that needs to take a load you need at least petg or asa (abs is a bit old now), which require proper storage.
also there are so much stuff that are in open prs and issues for years that are not implemented for slicers.
There are countless firearm receivers that have been printed on pla plus, many with thousands of rounds on them. Sure they may turn into a puddle in a hot vehicle, but they are functional and definitely take a load. Pla + is actually preferred in that community over the others you mentioned, although asa is becoming more popular, along with filled nylon alloys.
