I have a Sofirn SP10 and an Emisar KR4 both running Anduril 2, both have 2 brightness levels in lockout. I don’t know why your light doesn’t.
What makes you think it’s an ill-thought out design choice?
I’ve read a fair few of ToyKeeper’s posts/threads over the last few years and backwards thinking is not something i associate with her.
This is the Anduril 2 thread in which she seeks feedback for the UI:

Even just the first couple of posts worth a read if you want to understand Anduril 2 and it’s creation a little better.
