Mmh, all of these examples were done with vscode jupyter extensions... So they're definitely doable without forking.

Not trying to discredit the need for a fork though.

While you can technically do all of your examples (with extensions), it would likely mean that you'd have to either redesign the UX to limit it to where the extensions are good, or live with a somewhat unpolished user flow at times (because they're possible, but maybe not in the way the person imagining the UX wants.
