I am really confused, now. Who could possibly imagine that Twatt TB could
be viewed as an extension of Kent? Sure, it’s related around the lead end,
but is in many other ways is a wildly dissimilar method. It’s like saying
Francesca Surprise is an extension of Cambridge. While perhaps of the same
phylum, they are clearly of different genera.

Well, at least there’s some consistency to the argument, as Meyrick seems
as thoroughly un-Kent-like as Twatt.

Like the above, only even more so.

Amusingly, this seems the most Kent-like of the various “extensions” you
quote, and yet is the only one you assert is prohibited.

Are we on different planets?
