Why worry? It will make no difference in anything.

That's for a different reason. Spitters REQUIRE termination to keep 
losses predictable, and so the input port looks like the designed 
impedance. They require terminations that are the system design 

Switches do not. They care less about the open ports in unused

What application? With a splitter, it needs to be a resistance of the 
line Zo. With a switch, all the termination cap will do is keep the 
connector from getting wet if it is raining in the room.
