Server Screen Sharing toggle option

I'm part of the percentage that has the screen sharing options on one of my servers. It's a cool option, but I find it a bit intrusive and clunky. I'd really like to see a simple solution implemented:

A channel based option for allowing/disallowing screen sharing for that channel. Off by default. This allows people to use specific channels for screen sharing, without forcing anyone to see what they don't wish it.
