No...Just no. If we become locked down, nobody will come to your aid and find a new bootloader unlock method. See the latest RAZR HD JB update -- nobody has come to their aid. Dan, the dude who unlocked us in the first place, has moved on to other things and likely won't be coming back to reunlock us. We were only able to be unlocked because this was Motorola's first go on this platform and didn't have everything locked down 100% -- that just isn't the case these days (you'd see the X/Ultra having unlock methods if this was the case).
What'll happen is eventually someone will figure out how to root the damn thing again, Hashcode will update SafeStrap, and you'll be stuck using SSR and stock based roms. 6-7 months down the line when we're all running KK4.5 you'll wish you had a little patience.
The only thing we can do is hope that Moto has changed their bootloader unlock policies. With the G being a fully unlocked phone from the get go, there's always the chance that they could rethink some things and unlock us with the KK update, but that's very doubtful and just wishful thinking.
