I considered them a while ago, but Google has become a bit infamous for terrible/nonexistent customer service (even for paid customers), as well as random indiscriminate suspensions. Not a great combo. Don't wanna try my luck.
(But then again, I ended up getting a .dev domain at a different registrar, so I guess I'm screwed either way)
I would not use Google for anything that I wouldn't be OK with getting cut of without notice and recourse considering how infamous their customer support (or lack thereof) is.

That's pretty standard with any half-decent registrar.
