While I have never gotten my head around the details, based on the
arguments I have followed I think this may depend upon your definition of
“sound.”  While it may generate good extensions in most cases, there are
plenty of arguably worthwhile extensions it prohibits. One easily followed
poster child in this regard was Penultimus, but it is not alone.

I think you may have things a little backwards here. Including methods with
non-Plain Bob lead heads is not “broadening” what “can be considered an
acceptable extension,” it is merely eliminating an arbitrary restriction to
“only certain kinds of methods can have family names.” That is a very
different issue than allowing more possible extensions mechanisms for
methods of an already supported type.

We are unfortunately in a situation where “but we don’t know how to extend
them” could be used as an argument for disparaging interesting types of
methods. I don’t think that is happening explicitly, but I wonder if it
doesn’t at least contribute in subtle ways to ringers’ surprising
reluctance to try something different?
