CI4 doesn't support hyphens/dashes in controller subdirectories

Why app/Controllers/Sub-dir/Home.php ?
Should it be app/Controllers/Sub_dir/Home.php in PSR-4?

Because, as I've described, I need *hyphens* in my url for SEO optimization. If you put the controller at app/Controllers/Sub_dir/Home.php, this url does not work:

Code:

https://www.example.com/sub-dir

uri dash translation doesn't work. You have to use an underscore in your url:

Code:

https://www.example.com/sub_dir
