Yes, that makes a lot of sense if LED bulbs are used.
An incandescent bulb is fine as an oven light because the heat it produces goes towards keeping the oven hot, acting a bit like an extra heating element inside the oven, and only a small part of the power it uses comes out in the form of light. Since the bulb is being used where heat is desired, I doubt that the incandescent bulb would be outlawed as an oven light.
But other places where it may get quite hot (maybe a hood over a commercial stove) but additional heat isn't needed, piping light to where needed from a LED lighting source may someday become common.
In googling around, it looks like LED bulbs are targeted for 77°F, with a typical operation range of -25°F to 140°F (

Since LED bulbs typically have plastic components and the LED chips are solid-state technology, typical oven temperatures would destroy them and may make a bit of a mess in the oven. (See
Can LED Bulbs Be Used In Ovens?).
Since incandescent bulbs can operate at higher temperatures than LED bulbs, it may be necessary to make sure the fixture wouldn't cause the LED to run hotter than its designed operation environmental temperature range. So far I have been lucky since in the past ten years I have had only a couple LED bulbs go bad, and those two from a purchase of cheap LEDs several years ago, and I suspect the failures were the power supply in the bulb, not the actual LED chips.
