It'll be restricted, for one primary reason...
I'm not going to be the one responsible for someone's kid learning to make motors. That's an activity that the parents need to be involved in, and understand themselves, what their kids are doing.
I'm not interested in having people send me a copy of their ID card -- too much personal information on there that I don't want to have. Leveraging NAR and Tripoli tracking age works to my advantage, in this regard.
The reason it's visible to folks without access is so that those who might potentially be interested know it's there. But having it filtered beyond that keeps it from coming up in searches of those who aren't interested in reading it. An attempt to benefitting both.
As for requiring HPR certification, that's a judgement call of mine, and a couple others who are helping with this.
