Nope, on my last upgrade I ran a master backend and one frontend for
weeks while I ported and tested my local fixes. I didn't connect
anything with a tuner to the system until a couple days before the
switchover. It seemed happy as a clam. 

I've run tunerless backends for years. You may not have officially
tested it, but it seems to work. There may be issues trying to set one
up from scratch, but once you have a working system, setting up
tunerless slaves or promoting one of them to the master seems to work
fine.
