I'll bite.

I think there is an issue when querying as is it not possible to tell 
start time has not passed or end time has passed. Comparing start and end 
time with the local clock is a possibility and is likely to work most of 
the time. Still I think it is problematic that it is not possible to 
represent this with the state machine.

One possibility is to add a new LSM state named "Ended" or similar, which 
indicates that the termination ended (which is different from terminated, 
as moving to terminate now requires explicit action). It might be 
possible to move from "Ended" to "Terminating", by issuing a terminate 
request.


Bonus questions:

Do we allow modify after end time has passed?
- This can of course be site-specific (but in that case the answer is yes
   as we allow it at protocol level).
