**User story:**
As a Wikidata editor, I do not want to get false-positive constraint violations for items that use `P4224` (“category contains”) or `P360` ("is a list of").
**Problem:**
`P4224` ("category contains") and `P360` ("is a list of") are properties that should always just accept any qualifiers. This remains true even if the property used in the qualifier has a constraint saying the property should only be used in the main snak. Currently, these properties correctly often lead to false-positive constraint violations.
**Example:**
* Currently we have a violation on https://www.wikidata.org/wiki/Q7951553.

**Suggested solution:**
Include `P4224` in wgWBQualityConstraintsPropertiesWithViolatingQualifiers. That setting disables all constraint checks on qualifiers of statements for those properties – not just “property scope” (main/qualifier/reference), but also, for example, “type” aka “subject class”.
