Progress: cleaned up the oldest, grossest part of my code; so you can access the storage inventory while setting the shelves.

Old techniques are still fairly common. Not sure exactly what you mean by flat plane hair, as in alpha cards? I don't see them too much in games, usually blender. AAA has sidestepped the issue, they use TAA(or any temporal antialiasing) on high poly hair and let it smooth it out. If TAA isn't on, it will look like something from 2010.
In my game, I go for a stylized look so the hair is one molded mesh.
