In contrast to this point, as long as I use Xcode and do the same thing I've always done allowing it to manage provisioning and everything else, I don't have a problem. However, I want to use CI/CD. Have you seen what kind of access you have to give fastlane? It's pretty wild. And even after giving it the keys to the kingdom, it still didn't work. Integrating apple code signing with CI/CD is really hard, full of very strange error messages and incantations to make it "work".

You seem to be comparing a single dev sending apps to the world vs a corporate team pushing to employees (if I get parent's case right).

In most cases, just involving account management makes the corporate case 10x more of a PITA. Doing things in a corporate environment is a different game altogether.

Do you distribute OSS software which requires notarizing? If so, have you found a way to let the community build the software without a paid developer account? I would be very interested in a solution which allows OSS development, relying on protected APIs without requiring that anyone who builds the app to have a paid developer account.

Code signing is absolutely disgusting practically and philosophically. It has very reasonable and good intent behind it, but the practical implementations cause great suffering and sadness both for developers (cert management, cost, tools) and end-users (freedom of computing).

It is ugly: https://hearsum.ca/posts/history-of-code-signing-at-mozilla/
