This is incosistent in two ways:
1) Typical netlink behavior is to return the object being deleted.
Every other netlink user behaves that way - the only exception is sone
filters in tc and this is because they cant retrieve that detail
(something that needs resolution at some point). There is nothing that
xfrm_usersa_id provides that can be found in xfrm_usersa_info.
Same for the policy.

2) You cant have one behavior when something is deleted by pfkey and a
different one when it is deleted by netlink.

So i would recommend pulling this one out.
