Like Randy said, you'd want a wt forward of one type or another for saltwater and most fishing you'd be using a 10 wt for.
But wt forward heads vary incredibly as to total head wt. Some of them are only 30 ft long and others are 47 as can be seen here with the Crystal PE Fly line head weights
. So the AFTMA method only counting the weight of the first 30 feet is absurd when the entire head is meant to be outside the tip for most casts. 17 feet of head in the Crystal PE is not counted as weight in the line weight rating.
With the SA MEd 7 wt line, 37 feet of head weight is not counted.
So even if you already know what line wt works perfectly for you on a rod in one sytle of line from one manufacturer, change the head length (even using the same manufacturer) and you are back in the dark all over again.

Exactly. And it is also how shooting heads are labeled. Otherwise, they wouldn't sell any. The guys using shooting heads were just chopping and splicing their own till they worked right for them, then weighed them.They weren't about to waste money on something that had an arbitrary number attached to it.
But you never will see any change until a great many flyfishermen start bad mouthing them. Just as you never see any change in our korporate govt until masses of people start protesting.
I've already started. Your turn next Dan.
