Public bug reported:

When an instance is created, Nova adds a record in the API DB
'request_specs' table by providing the user request. That's used by the
scheduler for knowing the boot request, also when the instance is moved
afterwards.

That said, when destroying the instance, we don't delete the related RequestSpec record.
Of course, operators could run a script for deleting them by checking the instance UUIDs, but it would be better if when an instance is hard-deleted (ie. when operators don't use [DEFAULT]/reclaim_instance_interval for restoring deleted instances), we could then delete the RequestSpec too.
