Until Roc has separate tests, this isn't really applicable, but it would be cool to think about now.
Here's a POC of what I wanted in Elm, testing a new minor/patch version against a previous versions' tests.

Kasper Møller Andersen (Jul 05 2026 at 19:45):Happy to hear it’s not a strict enforcement, since I think that’s a point where Elm is too strict (since you are only allowed to publish a new MAJOR if you have a breaking change in some type signature, rather than any breaking change, period)
