To be honest I incorrectly assumed that no one (and I mean, no one) was using healing at events. That's what I get for mainly staying on the east coast. I have not been farther west than Indiana for the Olympics.
That said, I don't see a reason to dump the rules. I don't see healing as too larpy, I look at it as bandaging or repairing, and thus, not magical. If no one was playing by these rules, I would say get rid of them. Since we do have realms using them, better to keep them so they are more uniform.
