No SRE in the world that is halfway decent at their job would think that way. You never make assumptions about any kind of change, much less a global change to a completely different protocol. Doesn't matter whose fault it is. You just don't introduce any change that has a chance of unexpected behavior without rigorous testing, and you roll it out g r a d u a l l y, and you stop when error rates increase. Google literally wrote the books on SRE. For them to not know better is absurd.
