I remember being told ages ago that you shouldn't replace divots on tees in case someone has one under their foot when they can slip or something. Don't know how much truth there is in it.
On tee shots I always go off the side or back of the tee for a practice swing.
It's true; I've lost my trailing foot on one, and seen others do it. At least with a seeded divot you can see it & choose to tee up elsewhere. Probably more relevant on tees because you'll often be hitting driver & swinging a bit harder.
