When you proposed to drop Latn from the prefix I
was not sure about it, but finally arrived at a
"good enough" conclusion.

Dropping the script is consistent with "fonipa".
 
Keeping it is inconsistent, we have no "*-Latn"
prefix for "fonipa", because "*" is not allowed.

There are still obscure points in RFC 4646 where
it is far from obvious how 4646bis could settle
such issues.
