Track is dictated by distance from the front axle to the furthest grippable section, which is what "banned" the sphinx bars. Max width was 30 if my memory serves correctly, I believe that's why the London gb squad track drops flared out so much on the tops, then narrowed at the drops.

My guess is that the uci will soon take some more drastic road restrictions. I suspect they'll have some "safety" restrictions... Long computer mounts and the super tuck are probably also in danger (along with more clear sprinting rules)

Probably not until post Tokyo though, they generally have grace period of not changing anything close to the Olympics

Just my 2c
