I've used rest mode a few times to charge the controller and never had an issue with starting the Ps4 after. Perhaps they mean it auto shuts down after several hours instead of staying in rest mode, but that is pretty much a non-issue as far as I'm concerned.
India read something that said you needed to shut down the Ps4 and restart it to prevent the rest mode thing from happening and I normally do completely shut off the Ps4 unless the controller needs charging. So my normal habit possibly prevented me from experiencing any freeze issues.
Seems like it's a real issue, but it also seems like the seriousness of it is being overblown to FUD proportions.
