Movies folder structure needs clarification in the docs

[aureliendossantos]

The Music docs explains that you can use a "Artist > Album" folder structure. The Movies docs says that you shouldn't use a "Director > Movie" structure, but it's unclear why:

Movies should usually be in the library root directory or in a subfolder for the individual films. The subfolders allow for organization of metadata and images.

What does "should usually" mean here? What will happen if I try to make a folder for each Director and a subfolder for each movie?

For movie enthusiasts, such a structure would be as useful as the "Artist > Album" one. Currently, if you place all your movies in the root directory, they quickly become difficult to browse and sort.

Whether this feature is supported or not, I think the docs should be more clear and remove the "should" wording. If the feature works but needs specific folder names, the docs should indicate it more precisely.
