Obvious business idea: toilets that slide a containing partition before flushing. There's no need to use the seat for that, or to require the person to get up.
There might be easier mechanical ways to accomplish the same.

Edit: retrofit by sucking air through toilet cistern overflow pipe e.g. https://www.panfan.co.nz/ (great name) but heaps of similar (loofloo, odourvac, airaway, toiletfriend, expella, clo-vent, etcetera) but probably want a Japanese toilet with it inbuilt so designed to suck air from all around the rim, not just the downpipe? Disclaimer: first time I’ve heard of any of those products.
I had this idea mostly for smell control - why remove all the air from the room instead of just dealing with smell where it is created?
You could probably rig a chain that connected from the front of the lid to inside the tank that disabled flushing if it wasn't fully extended -- given the handle itself is connected to a chain.
Of course, that could be solved with a see-through toilet lid, but I can only imagine the absurdity of trying to pitch that to consumers.
