If a file called .nomedia gets put into a directory, the Media Scanner skips that directory, e.g. sprite images.
Does that also work if .nomedia is a folder?

Yes. If a folder contains another folder that is named .nomedia, the parent folder will be ignored.
The relevant code is here (note to the confused: File doesn't necessarily be a regular file - in Linux directories are just special files).
One of my favorite IME app also creates folders of this name (instead of files) in its asset folders - the assets are ignored by MediaScanner.
Trivia: If you managed to put other special files like symbolic links or named pipes (FIFOs) with the name .nomedia, it will also work. (Spoiler: indeed you can, but you need root).
An alternative way, as suggested by beeshyams, is to rename the parent folder and make it start with a dot. This has the same effect as having a .nomedia inside it, as both ways make the code return true (should be ignored).
