The administrative state is to change a connection's state, so its
use is not just for deletion, although that is what's defined now.
The object needs to be processed on every node of the path, so Path
and Resv is a nature choice and is what RSVP do to
change/modify parameters or a connection/reservation.

As I said in my last email, deletion performance
in a normal deletion scenario is not a major concern.
Do you have a real performance target that you can not
achieve because of the extra objects in the Path and Resv?
If so, can you share with us what they are ?
Otherwise, I guess we have to agree on this disagreement.
Or others can speak up :-)
