By "knowing the current state of thread support",
do you mean finding out whether the remote target
supports thread debugging?  

If GDB sends the remote target a request that the
remote target does not support, there is a well-defined
way in which the remote target should respond (I believe
it is by sending an empty response).

I don't understand.  GDB implements the remote protocol
for thread support.  There are queries defined for asking
the target for the current thread ID, changing the current
thread ID, asking for a list of "live" threads, asking 
whether a particular thread is alive...
