Perhaps failing on the first breaking test is something that would be wanted in certain situations. Would adding something like --fail-fast=false be a good new API to get around this change of behaviour?

Yeah I've wanted this for awhile. I think --bail and --no-bail would be the best flags (with --bail being default). The meow CLI we use supports this --no- syntax automatically
