My parents have a ceiling fan that came with an LED light, which broke. It was barely under warranty for the LED part still and the manufacturer sent out a new light module, except they've changed the fan a little over the years and the new module doesn't fit on the old fan... they ended up having to send a whole new fan.
They don't care if bulbs are replaceable, since their lifetime is limited to build -> sell.
IMHO, pretty unnecessary, as once the PAR30 dimmable LED bulbs got good, I don't think many people would prefer incandescent. OTOH, I think they were pushing compact fluorescent, which I don't think ever got very good.
For new construction now, the LED fixtures can be mounted without a can, because they put out way less heat, and some of them are very thin, so they may not penetrate beyond the thickness of the ceiling, which is neat. But for retrofitting, putting a screw in bulb is nice and easy.
The home LED market is pretty fractured and there's not all that much brand loyalty. (At least at the lower level where companies churn out lowest cost LEDs. The companies that bet on brand loyalty tend to have somewhat better quality.)
Everyone I know who complains about LED bulbs failing, you ask them and they admit to buying the cheapest ones they could find.
At that point, I decided to just buy the cheap ones because that was easier than dealing with the warranty process anyway.
It depends on the cost curve. When the technology has matured, the cheap ones might be good enough, too.
Eg approximately all tooth pastes are equally effective, so you might as well go with the cheapest one that agrees with your taste buds.
My issue with LED bulbs is that they don't fail per se, instead they get progressively less and less bright over time. It's a slow fade rather than a sudden explosion.
(I've gotten into the habit of writing the installation date of all new bulbs on the stem as I insert/install them. Just because I want to track how long they last.)
