There is a pretty easy workaround, just make a file in a directory that doesn't exist and it will create the folder for you. It's a bit obtuse, but nothing terribly hard.

For a game development package that's been around for more than 10 years, I think its ok to have an Add Folder feature.

If they're going to add a feature that does nothing but create empty folders, then they should probably make empty folders show up in the file tree first.
