Blocked by #9823 (that item will decide the fate and possibly resolve this)

Context

Initial proposal of BuildAnalyzerRule has a Category field:

However it was not yet decided how that will be used and if that should be a freeform text or fixed enum.

Goals

• Decide whether we should bring back the Category and what would be the usage for the field (e.g. mass-configuration of rules by customer, or improved UX)
• If decided that it's needed:
  • Document the usage and expected configuration by custom Checks authors
  • Reintroduce to code
