Until today... Screenshot from Android phone - https://ibb.co/KD27YGL
Pushing hard is pretty subjective, I don't see a "hard" push to turn off security features. As a matter of fact I've seen warnings about disabling the lock screen.
So I would agree, it's not a hard push, Google is def nudging people towards less secure logins. My S10+ asked me this same question about a week into owning the phone, but it never bothered me about it again once I declined. And at no point in either system was the I made aware of the risks I was accepting if I enabled it.
So, not a Google specific issue, but it's a less than ideal approach considering how sensitive peoples phones are today.
It's unclear what "smart unlock" actually is, but as far as I can see it means my phone can be unlocked just with a swipe.
