That may have been a concern (I wasn't part of the conversation) but I don't see how the current implementation could do that. If a normal "guix build foo" fails, then it's a busted package period.

I'm glad for the "without-tests" option because when I'm working on packages with a test suite that takes more than a few seconds, I like to make sure that the rest of everything is working before I start running the tests.

Another thing I'd like is an option to build a package reusing the state from a previous build. If a package I'm working on takes a minute or longer to build and I'm having some sort of difficulty, it's obnoxious to wait for that to complete again after every cycle. It could be near instantaneous if I could re-use a cached build, which is doable in Docker, Earthly, and other containerized build systems.
