Flu lamp ballast

I was wondering why is it that some of the LED flu lamp replacement tubes say to leave the choke in circuit I don't see what good it does apart from dropping a few volts also I would think the little voltage Spike at switch off wouldn't be helpful either

I guess its easier/cheaper .... maybe a selling point as don't have to modify the fitting?

Its also going to be wasting power. The ballast will still have resistance (as well as alot of reactance) so there will be an I2R power loss. Only a few watts but its still makes the whole fitting less efficient.
