Make Document Library identify the file types by their magic number (file signature) instead of filename extension

The document library identifies file types by their filename extension, allowing files to me misrepresented (e.g. a PHP file can be uploaded as a JPEG file type).

Due to a customer request on ticket #5282, I would like to propose the idea of creating the possibility to switch between file type detection by extension or by it's contents (using their magic number/file signatures).
