Yes. Eventually. Or, more practically, do it right in new construction.
I sense great commercial success here, telling people to run LV to every HV can light. And how about--you know--a lamp? Like the one standing on my floor right now, with nowhere to place an external box? Should we redesign them all for this new standard that doesn't address actual pain points? How do we power the control boxed? Does every lamp now have a chaining 120V and you need to hang an AC adapter off it, then weasel control wires into the lamp shade? Or do we expect them to output 12V in case you want to run them with automated controls? Or do we expect them to just pick a vendor, build in their control box and you throw out the lamp if the software sucks? In a lamp?
This solves a problem people don't have through the time-tested strategy of making people think more, do more work, and be more annoyed. I think I'm seeing why it doesn't exist.
(And yes, I know about 12VDC lights; I have a studio full of them, with DMX controls. They're not consumer-friendly.)
How do you propose to do this in a lamp or a can light with a standard light socket? Should I rip open my ceiling and add control wires to every can that's in there?
These bulbs don't have the smarts in them just because nobody thought of doing otherwise. The world is mostly made of legacy infrastructure. Hue will sell you lamps that don't use E26 bulbs, but you're not going to be changing the lights out later if you want to use something else.
