Out of interest, how did you see that coming? The discussions I remember here on HN were full of people wondering why, and being generally blindsided by the news...
I didn't see the writing on the wall for them shutting it down, rather that I could not rely on it.
I have (or rather had) two Google Domains accounts, one for my own projects, and one with my work email address for work purposes. My work Google Domains account got banned for some imagined rules infraction. I sent an appeal with evidence, which was immediately denied. In case you are curious, the effect of being banned from Google Domains is: you are no longer able to use Google Domains at all, which means you are both unable to change your DNS settings, and unable to transfer your domains out. For all of the domains, I had to wait until they expired, wait for the grace period to expire, and re-register them on a new registrar, hoping nobody else got to them first.
After this experience, I decided it was not worth the risk to keep my personal domains on my personal Google account, so I transferred them out a few days later. I assume this was a bug, but as soon as I initiated the domain transfers, Google deleted all DNS records, which meant I had some non-trivial downtime on all of my websites while I got it all sorted out on a new registrar.
After both of these experiences, there is no way I would ever trust another domain to Google Domains.
