This seems a retrograde step:

This sentence, as written, appears to trump sections 5(a) and 5(b), below,
and disallow plenty of currently legal peals of doubles and minor (and
minimus and doubles, though I think those are less frequently rung in
practice). If it doesn't overrule them it certainly conflicts with them,
which is also Not A Good Idea.
