UI improvement we discussed already documented via https://github.com/bpmn-io/internal-docs/issues/665 CC @YanaSegal.

I've tried to push out an initial version of this thing as a preview, hidden behind a feature toggle. Unfortunately I failed in the timebox I put for myself.

What I wanted to accomplish:

if (Flags.get('bpmnlint-recommended-rules', true)) {
  registerClientPlugin(recommendedRules, 'lintRules.bpmn');
  registerClientPlugin(recommendedRules, 'lintRules.cloud-bpmn');
}

Why this failed: We eagerly load all internal plug-ins and cannot use flags that early in the resolution. We could load plug-ins after flags (and meta-data) are initialized; that would be my expected behavior. But given how we currently structure things that is not a quick task.

We could load plug-ins after flags (and meta-data) are initialized

I agree with that.

Should do, as soon as we have settings.
