Is this yet another service to be added to Google's graveyard in a few years time? Domain registration is not Google's core business and I can't see it being massively profitable(double digits), so it will likely face the chop soon. I am sure they will offer a way to transfer your domains, however, why go through this pain when the outcome is inevitable. My rule of thumb is to only buy a service of a company if it is their core business and customer retention actually matters to them. If Google Domains gets shut down none of the share holders will suddenly panic, it probably won't even register. As a result customer retention and satisfaction will not be very high on the priority list.
