This is not good.

I've spend literally days attempting to get a Python-based GUI application "signed", using every available packaging option and dozens of different approaches recommended by a multitude of different sources.

Absolute failure -- and no usable error messages indicating what might be wrong. Just basically "no, you can't upload that.".

This does not bode well...

Sounds like it's working as Apple has intended.

I think that's the biggest issue with code signing, Xcode should come with a "Sign and Notarize.app" that allows you to sign anything you point it at with a single click.

What, in the past 10 years of MacOS development trends, suggested to you that anything was headed in the remote direction of "boding well"?

Admittedly, I've done 99% of my development to target Linux, and just happen to use a Mac for its simpler and less time-consuming day-to-day GUI management.

This is the first time I've tried to develop something to target a macOS installation -- and it was a train-wreck.
