This is currently only the basic idea of the change. I haven't updated any definition (apart from the one of grid component role) yet.
Also, grid component had the subclasses (gas | heating | electricity) grid component. The same motivation for the removal of grid component should also apply to them, right?

@ColinHDev sorry, for not being clearer: the former class grid component (OEO_00020006) should stay grid component but become an equivalent class 'artificial object' and 'has role' some 'grid component role', where you create grid component role newly. Like this, the concept of the class isn't changed too much, in case it is already being used somewhere.

So like this?

Yes. Please add to the def of grid compnent a sentence like "It is defined via the grid component role."
Please also update the header to summarize the content of this PR and add term trackers to grid component.
