Mm, I was worrying along similar lines when I wrote Ray offlist, and this is the context in which he mentioned [1] as being an innovation that would count as "unique".  Perhaps this is some weak justification for keeping it?

Certainly not the *second* one?  It's [D] for which I see most clearly what Ray meant: as he writes in
there was an early frication of original intervocalic voiced stops in (this part of?) western Romance, including [d] > [D].  I can't think of any direct Romance survivals of this [D] atm but English attests them, in e.g. _faith_ < an Old French _feid_ with dental fricative < Latin FIDEM.  

(Brithenig can be seen as retaining this [D] too, though I don't know whether Andrew Smith meant that of it or whether it was purely a bogosity.  The rest of its dental fricatives are inarguably bogus, I think.)
