Grid subdivisions

As of October blender has the ability to set a custom grid subdivision. [Theeth’s commit]

However I can’t figure out how this feature can be accessed via python. Is it even possible, or should I file a feature request for this?

if we did this it would not be as simple as Get/Set Gridsize because its view spesific.

Maybe
Window.SetGridSpacing(winid=active) # where active would be the default if no window ID was given. again another API question that might better be asked here

Ok, thanks for your input.
Just sent my question to the python mailing list.
