Nice!

So this would need a fork to be usable on chain on bitcoin?

This solves the mathematical problem of creating a single small signature that signs all the inputs of a given transaction?

And today (without a fork) we would need to include that signature replicated in every input

Yes it needs a soft fork. The important thing is there's a solid theoretical basis for actually doung CISA. Experience with MuSig taught us you have to be super careful building these algos ... the power that Schnorr's linearity gives you is a double edged sword.
