Yes, I guess not signing our builds (except releases), and asking
testers to use Ctrl-click + "Open" instead of double-clicking, is what
we'll do as a workaround, if it turns out there's no way for a user to
launch a signed build without it being notarized.

It's just a bit of awkward, I sort of liked how we had set up our CI
so that every build is essentially built like it was a release (well,
with the exception of this notarization, which we only do on tagged
releases due to the time it takes).

Yes, and it doesn't help that the notarization process is rather slow.
Oh well, one only has to accept it.

In one of the WWDC 2019  talks about security and code signing/notarization, they mentioned that this was true for applications built (or maybe it's signed) after some date in early June. For example, Qt 4.9.2, released June 26, 2019, will not run on Catalina beta 3 without knowing how to work around the notarization requirement.

An application built with the 10.14 SDK or later must enable hardened runtime in order for it to be possible to notarize the application, but it is possible to notarize applications built with previous SDK versions for which hardened runtime did not exist.
