v22.5 release, the Advanced Drawing Mode selector has been removed. Why?

I honestly thought I had a bug when I could not change the Drawing Mode in Advanced Settings in Preferences, Performance. I searched everywhere looking for answers and I just now came across this (screenshot below, which I highlighted in yellow) by accident, trying to find out why I was missing that option to change the Drawing Mode.

Is this connected with 3D features that have been removed? I have read the release notes for 22.5 but can't seem to find any reference to the Drawing Mode. I may have missed it.

Just need to understand the whole thing with OpenGL. I would love to know!
