I touched a lot of super calls in #6629 and #6613 but there are several remaining occurences that haven't been using the current class as first argument and/or the "bound argument" (first argument of the method) as second argument.

I believe lots of them are actually bugs but some of these look intentional. It could be worthwhile to revisit the remaining ones, just to exclude potential bugs and in case it was accidental to remove the obsolete arguments.
