It's been a while but I'm pretty sure signing and notarizing is required on macOS now, without disabiling SIP. At least for things downloaded from a browser. My interpretation is that $99/year is required if you want to avoid your users needing to use the terminal.

If they’d simply allow the same on iOS, I’m willing to bet that essentially all of their lawsuits and regulatory scrutiny would disappear overnight.

Right-clicking an app bundle and clicking open gives you the option to run the app even if it's not signed and notarized by Apple.

This doesn't work if the app is quarantined.

It's not required. I made a macOS app recently and no way in hell am I paying that $99/year. People are still able to run it. But there is a scary warning.

On my own Mac I keep gatekeeper disabled.

You can still run an unsigned binary using right-click menu > Open.

Ahhh. I thought that there was still a button in "System Settings" -> "Security" (or similar) that let users launch an unsigned app anyway.

But it could indeed have been removed in some macOS version without my noticing. :)
