Consider adding the IAO:0000231 property to indicate the reason for obsolescence. Other obsolete terms in the codebase follow this pattern. For example:

property_value: IAO:0000231 "terms merged" xsd:string

This property provides metadata about why the term was obsoleted, which is helpful for ontology users and maintainers.
