I get that it's a cooperative action and you're not walking up to someone and reaching for their hand to give it a firm non-consensual handshake.
But making fine distinctions like this reminds me of the Simpsons gag of closing your eyes, repeatedly punching the air, and declaring "I'm not punching you! If you walk into my punches that's your problem!"
I prefer firewall-like rules. If you touch a NO spot it's a violation, and if there are cooperative circumstances then you should add those as another color. Although of course to communicate these rules, a .png wouldn't do, you'd need some file format with layers. Base layer: "touch OK in a medical emergency or to shove me out of the path of a train"
