A planet could handle traffic volumes of thousands of ships a day and never get into the slightest trouble, if there is a ground station handing out jump clearances to all leaving ships.

You're definitely seeing this clearly - the only assumption is that ships 'move' while entering HS.
If a ship does or can make a static jump from a point in real space to a point in hyperspace, and can then start up an accelerate away - it could occupy the entry sphere for as long as it wants.

Still, you seem to have boiled to problem down to the same basic issues as any hyperspace system has - knowing if/when there might be another ship on the other side of your jump point.
