Comment (by hideishi):

 I would like to highlight that **WP_Filesystem() SHOULD NEVER BE CALLED
 WITHOUT CREDENTIALS** unless you are 100% sure that FS_METHOD is 'direct'
 because since 8.0 PHP restriced type checks that throws fatal error if
 invalid type of argument is passed in ftpext and ftpsocket functions.
 I haven't tried with ssh2 but I guess it is the same for it as well.
