@aaron do you think there is still anything for the Wikibase team to investigate here?
If not I might just close this.

I see EntityRevisionCache and CacheAwarePropertyInfoStore seems to use set() on invalidation. Also, EntityRevisionCache
and CachingEntityRevisionLookup, and PopulateInterwiki seems to call delete() on a non-WAN cache instance.

CacheAwarePropertyInfoStore is solved with T218197
