We did spend some time discussing it and the decision has been
mentioned on this and/or lsb-spec list a few times since then, but to
be honest I don't remember the details. Maybe someone else who was
there can remember better than me.

As you've discovered to take the common subset of functionality
between the two versions of sets of commands (and its not limited to
passwd and chfn) its necessary to both remove a number of options and
add extra commands to the specifications. I'd consider this to be a
significant change to the specification and not just a fix of
something obviously wrong.
