I doubt it would raise any red flags. In Vintage Motorcycle circles, there is a very popular Puddin' Bowl helmet made by a respected helmet maker that states it does not meet current saftey standards. Folks were them, get pulled over, go through inspection traps etc. and the helmets are never questioned. It's not that they're not noticed, they look very vintage, it's just not something that's checked.
In the event of a crash, your insurance company would have an opinion on the subject for sure.
