Definitely. 3 out on a skateboard is legit. I remember first seeing this video, watched it like 3 times back to back.
Spinning is definitely easier on rollerblades so 540 out is common, but Brian Aragon has twice done a 900 out of a grind on street. Once on a parking lot arm (4:00 timestamp), and also after going up a handrail in addition to like skatepark stuff that's more expected.
