While Google's registrar seems ok right now, Google's support is nonexistent when things go wrong. Literally every bit of their support is outsourced to 3rd-party companies that provide no path of escalation.
Even the really bad registrars (and there are a ton) usually have some direct support (or resell off enom, which will extort your money for the privilege of bailing you out).
That's the point. Domains causes no problems. Only in some weird scenarios, things can become troublesome. In those cases you need a support. In others you don't.
If you have a domain registrar with a good support, account the premium you pay as such: a premium for an insurance when things go bad.
