+1 to Nils remarks. Please also consider backward compatibility. If you remove a bunch of things, I'm probably just going to have to add them back on cocalc to avoid all the headaches of people's code breaking. There might be a ton of random code out there that will break if you remove a bunch of imports.
It would be nice to have a different entry point to Sage that has *dramatically* less imported by default. By I don't think it should be the default, just because of backward compatibility.
