I suggest we add a property similar to sh:description and rdfs:comment, with the explicit goal to be used to communicate the semantics of a shape with AI agents that understand natural language. Particular use cases are:

• constraints and rules that cannot be formally expressed in SHACL
• for users that are not familiar enough with SHACL to formally express them
• maybe as a textual starting point to formalize semantics later

Examples etc are in the PR #726
