Yes, my Gmail inbox is full of regular senders being flagged as "possibly unsafe" and I need to click a button "Looks Safe" to accept them. They are not being spamboxed, but they are definitely flagged. Even official communications from the USPS!
The reason given is that "Gmail hasn't scanned this message", so I suppose the scanners are unavailable/disabled for the time being.
They should also be tagged as "Important" but they are not. I believe this is a heuristic-based designation, and it has not been working too great lately. My most important mail is coming through as "unimportant".
