These would be much easier to do with LEDs but somehow they didn't survive the transition.

Who’s wants upward directional lighting at ceiling height? They were a horrendous design that only lit the room up, not great for reading or crafting.
People who want the entire room lit up with fairly soft lighting?
It only lights the ceiling up, you still need additional lighting for anything you want to do. And halogens are not soft lighting either.
Those were designed so the heat wouldn’t get trapped in the lid and the are super bright, so you couldn’t point them down. Replacing it with LED you wouldn’t need the same design considerations, and just replacing it with a led bulb won’t make it work the same.
These were just a shit light altogether, it’s why it didn’t “survive” the change to led. The efficiency is also worse because of their design.
Most upward lighting comes from the floor or lower down the wall, so it actually floods the room. Theres a point to upward lighting, but not at ceiling height and sending it more up.
It’s using the ceiling as a diffuser to soften it. Same way that photographers don’t normally point a light directly at a subject but instead use a diffuser like this

I agree that LEDs would probably work better with some kind of frosted glass as a diffuser but there are some high lumen LEDs that would work. They do get warm but not halogen warm.
When I take pictures of my cats, I blast my Emisar DT8’s overdrive mode at the ceiling and it diffuses the light PERFECTLY for sick, sharp cat pics.
