[TYPO3-core] CGL violations "unused parameters"

[Roland]

hi everybody,

can someone please tell me if i can fix those CGL violations just by
deleting the unused parameters? or are those unused parameters there on
purpose?

according to sonat in total there are 400+ unused parameters in core. i
could fix that but am not sure if there were some pitfalls...

kind regards
