Guessing from how this change required 3+ implementations before it became official according to the gitlab page, maybe it’s a chicken and egg situation. Hdr is a lot of work so maybe people don’t want to implement an unfinalized version that might change
“Can’t live without” is an overstatement, but here are mine:
Kvaesitso, search focused android launcher. I used to really like nova launcher’s local search and navigated my phone mostly using that. But once gensture navigation became a thing I had to stop using nova and replicate the experience in Samsung launcher with various local search apps that were lacking in comparison. Tried to go back a couple times once gestures with 3rd party launchers got better but found my old setup still too ugly and sluggish to go back to. Recently I randomly came across Kvaesitso on fdroid and it was everything I ever wanted out of a launcher.
Amberol music player. Not the ideal music player I’d like but at least it’s not Elisa.
Kid3, audio file tag editor. It has much better workflow/automation than mp3tag that I used in windows, and it seems if you spend some effort on it you could add more automation to make it even better.
