No, but the convention has been to only pass the self pointer to
functions that may be called before init(), and to init() itself.  The
rest may use a global variable (declared static in the fmt file), which
is either the only format struct or a pointer set by init().  I see
little reason to single out clear_keys().  So I oppose this change.

What formats would use this?  Is this e.g. for sharing of clear_keys()
implementation between several formats (which)?

Thanks for asking!
