The SSO example is really different from the other ones. We've got a few standards implemented there and the authN/Z interaction is well defined. For other systems we don't have that. It's a customer in one system, page viewer in another and a spreadsheet row in the billing service. Even with some common format, there's just too many specialisations you need to rely on custom fields. There's a good reason zapier has an option for "just give us the code to run".
