Many kRPC types can't be directly imported. For example, the Vessel type is only accessible like so:

from krpc.spacecenter import SpaceCenter

vessel: SpaceCenter.Vessel = ...

It would be convenient if, for example, the spacecenter.pyi stub could export those types directly. As an example, in my personal kRPC workspace, I've added additional (non-comprehensive) files to make these types easier to access.

(I'm unsure if this is an issue with base kRPC or just nullprofile's fork, though I suspect the former.)
