>>Yes, you can: filter your primary key index on NOT DELETED(), and deleted records won't bother you. However, this has a drawback; since filtered indices won't be used by Rushmore, you will need to add a regular index on the same expression, so your queries can be optimised.

SET DELETED and INDEX ON FOR DELETED() are two different issues. You are correct that SET DELETED will still prohibit the reuse of a primary key. INDEX ON FOR DELETED() will not.
