Maybe this could be a prosumer retrofit thing, where the AC voltage gets converted to DC in the junction box, and then DC is sent down to the fixture.

Probably with some sort of current sensing system to make it compatible with dimmers.

Pair that with DC A19 LED bulbs that have no internal power systems.

Probably expensive to put together and to install, but if the goal was to have LEDs that last longer, that would do it.

The problem is that in 99.99% of homes outlets are on the same circuits as light fixtures, you would need to do some major rewiring.

No, I'm saying you put a module into the junction box that the light fixture is attached to that serves as an AC/DC adapter, current limiting driver, and possibly a dimming sensor that would then provide downstream DC voltage to retrofit A19 bulbs.

Those bulbs would then have no internal switching systems to burn out and rely entirely on the module hidden behind the wall to handle their power needs.

You will see need to current drive the LEDs, DC alone won't help.
