Question for #ActivityPub implementors: has there been any research on how to best handle deletions (accounts and/or posts)?

At the moment, the best (and only?) way to know that an account deletion has been federated everywhere is to notify any known inbox / instance, for every account deletion.

This is very wasteful and not efficient, are there any alternatives? Has anyone worked on this?
