Ideally I agree, but I’m not sure it will be effective. There needs to be concrete consequences, and there’s a lot of room to hide.
If we required something like a P.Eng, which (at least theoretically) means you are responsible with real consequences (for say bad building design) then certified employees will be far more reluctant to attach their name to shoddy practices. This bubbles up to the employer. If a client requires you to have certified P.Eng sign off then there’s some reassurance it’s not just going to fall a part.
I don’t think you need this for everything in a stack, but security wise it might be a good idea.
