NHRA tracks are more strict than IHRA. Yes, Cobra Verts need roll bar and at least 5-point harnesses (with current dating on them). I had my car outfitted that way a couple of years ago so I could run anywhere. I also have a halon fire extinguisher attached to the roll bar with a metal clamp, another requirement.
These are not new rules.
Look my car up in the member cars area on SCMC web site to see how it's outfitted. My best times were set at NHRA track in North East, Maryland during a Mod Motor Shootout a couple years ago.
