Actually, from what I read in the Beacon Permissions thread not so long ago, this isn’t the current plan.
My take from that was that you won’t be able to allow people permissions to just use interactive blocks. That permission will be intrinsically linked to the ability to break interactive blocks too. Tbh, the fact that this system doesn’t allow for the very thing you’re suggesting seemed like a notable flaw, but at the time that I thought of it I didn’t have time to make a decent post and, uh, may have forgotten until it’s brought up again now
