More compact lenses are a constant improvement, but one of the main things here is just moving compute and power off of your head. Which many have done before.

Honestly I don't know why that's not more common. I've used puck-based ones, they're great - far less heat and mass on your face is a major benefit. They're also usually easier to plan upgrades for, as the two most costly pieces (which do very different things and have very different progress cycles) are separated.
