i guess you wanted to say operate on $ru - strip() and strip_tail() functions - indeed there are some core functions, removing might not be easy since some people may want them for backward compatibility or simplicity, but moving several "no-longer-often-used" core functions to a module would be good.
in my opinion, we should remove old $ru specific functions, when more general solutions become available. it is not a big deal to make the changes in the script.
