Did per-pixel lighting ever get implemented?

All I'm finding about it are (non-community) articles from mid-2017 saying gzdoom would have it soon, but no sign of it in release notes or anything like that. If it has indeed been implemented, what's a simple wad that shows the effect the best?

Everything that uses dynamic lights, maybe? Those are done per pixel.

What are you expecting here? Per-pixel application of dynamic lights has been a thing for many, many years. Glow gradients are also done per pixel and the advanced light modes like specular or PBR cannot be done any other way.

Textured dynamic lights have been discontinued a long time ago.

I guess lighting that would reflect off of a section of a weapon instead of the entire weapon.

If you got models with PBR textures that would be possible, but there is no magic wand to create effects where none are defined.

Weapon sprites are not lit per pixel. Weapon models are, though.
