Or bring your own plug in lamps. On a side note, it appears that in Australia, the light fixtures plug in so renters *can* change them as Dave did in his lab.

Why does it even matter? It took some work to design a suitable retrofit LED bulb but now that has been accomplished, they are quite good, inexpensive and reliable.

Except that bulb has not yet been designed at all.
Ceiling fixtures are a common use case. There are zero bare bulbs or bulbs in table lamps in my home but there are many ceiling fixtures. And these bulbs fail in such fixtures. I have tried many and thrown away a lot of money in the process.
You can define away a problem if it makes you feel better, but if your question is why do people not run out and mass adopt these otherwise wonderful "retrofit" bulbs, the answer is staring right at you.

That's funny because I have dozens of these bulbs that haven't been designed yet in my house, many of which have been in service since 2011 and they work just fine. A majority of the lights in my house are enclosed ceiling fixtures, I did have a few early LED lamps fail but most have been fine, I've almost forgotten what it's like to change a lightbulb.
