I do not think it is a good idea to start implementing everyone's custom vim keybindings in the webapp. Maybe some day there will be the possibility to configure the keybindings as a user.

I have never used vim keybindings, so I don't know, but if "jj" is non-standard then we can indeed not support it as default. Maybe we'll support custom keybindings at some point.
