[Star Wars] Why don't lightsaber users quickly turn their lightsabers off and then on to get around parries and blocks?

To elaborate, let's say that you're swinging your lightsaber towards your enemy, and they put their lightsaber up to block your blow. Just before your saber makes contact, you switch it off and once it is past the enemy's saber, you turn it back on and continue your swing.

* Most Jedi and Sith are precognitive, meaning this gambit wouldn't work nearly as effectively as against Force insensitive people (who presumably can be bisected without fear anyway).
* Lightsaber ignition and dousing is not as fast as all that, in a fast-paced duel the tactic would be as slow as a haymaker.
* If your blade is past theirs, their blade is past yours.
* Sudden changes in the gyroscopic force on the hilt would make the move difficult to execute with precision, and the time to drill would be better spent on finessing your form or maximising your Force abilities.
* For some reason lightsaber users rarely give point, despite it being a big deal in most fencing.
* If you're going to be that pragmatic: use a blaster in your off hand and learn how to bind the opponent's blade and then shoot them.
* How the hell do you even practise this without killing your partner?
