The answer may lie in the fact that the US does
not have one single recognized plumbing code;
accepted practice varies across the country.
And even locally, there may be exceptions to
the published code(s).
So it's hard to say. But as you noted,
wet vents have pretty much gone the way
of the horse and buggy.
