Are these genuinely being hand rolled in an enterprise environment? Unless it’s completely impossible to automate then I can’t be sympathetic to companies that are just doing it wrong.
There's lots of equipment that can't accept certificates automatically. If they can, it might be in a closed off way that's difficult to impossible to reverse engineer. If you can, that's still a lot of skill and labor, which drives up the cost. They also might find out that it would be insecure to do it automatically.
