It is a risk. I had a problem with my Google account, and while I was able to find a human to email about it, they were completely unable to help. It was literally "you have to do the thing, even though it makes no sense, because that's what our algorithm requires" (in my case it was repurchase an old domain in order to prove that I owned it, so they could cancel the account associated with that domain. Literally makes no sense, but it was the only way their process could work). That was my "ruh-oh" moment when I realised their products are basically unsupported and therefore shouldn't be used in production.
What happens if the domain-name is repurchased by someone else or claimed by Sedo, etc?
I figure that they either never thought through this process, or it was deliberately designed to make the cancelling process as awkward as possible. They're smart people, I think the latter.
So if they're going out of their way to be inconvenient to me, I'm going to go out of my way to never use their stuff.
