How long?  A day?  A week?  What is to stop the registry from
automating a process that resubmits the reserve every expiry period?
I remember back in my mainframe days, I used a system that kicked
idle users off the system if they were idle for 60 minutes.  So the
hackers just put together a program that made the user look active,
thereby causing more of a memory and CPU load on the system, when in
fact the interest was to reclaim memory which was in short demand at
the time.  Perhaps limiting the number of reserves a registry can
have open at any one time and perhaps a second limit on the number
of reserves a registry can issue per month would solve the problem.

You should make mention of grandfathered .com DNs, which were
registered years ago and don't have to pay nor be renewed.  A very
large TTL should be used here.
