I suggest you try it. I'm guessing you tend to question everything, so why not just answer your own question?
Yes, I do question everything. I feel like that's a good trait, but anyway.... When I am able to get my own equipment, if nobody has told me why it's a bad idea, I probably will try it, just to see. For now and probably the immediate future, I will be using rental equipment.
I know I'm inexperienced and ignorant. I *think* I am capable of learning from other people's experience, though. So, I asked here in case there's some reason that it's a bad idea and I just don't see it because I'm inexperienced and ignorant. If I thought I knew everything, I probably would not ask and would just try it.

I don't even notice that it's there I'm not sure what the OP means by obstructing view, since it's under your chin
If it's preventing you from lowering your chin to your chest, then I'm guessing you can't see your own BC belt buckle. If it's hanging a bit lower, and you can lower your chin to your chest, then a reg resting on your chest just below your chin seems like it would obstruct your view of your belt buckle. Either way, you would not have a clear view of your lower torso. At least somewhat. But, I'm gathering from the responses here that, in the real world, that bit of obstruction just doesn't ever bother anyone, so I should probably figure that it's not going to bother me, either.
