Gatekeeper and notarization are not silliness. They exist for a reason. I thought it would be a good idea to release the app during development when I am sure that it works correctly and then maybe get some feedback from early users.
I guess OP's point is still pretty valid though, what's the harm in signing and notarizing it?
They aren't silliness, they are levers of control and loss of freedom
Ex-Apple macOS/Xcode dev here.
I just downloaded your app and ran it through hopper. There is a LOT of embedded Apple Script. I would never run an app like this with SIP disabled or without an active network blocker.
Your app requires direct access to major OS components: code signing, even during alpha should be a requirement.
