If by seriously you mean am I trying to think outside the box and be inclusive, then yes I was being serious.
If you're not trying to cater for the less mobile, then why bother with the seated class? Why not simply say, FT courses include standers and kneelers and if you can't take them for any reason you get credited with a miss. It's a physical sport so if you can't manage it, go and do something else.
Naturally, anything that breaks the mould is going to be resisted by the leviathans.
