I personally don’t care about being friendly to authors who are not 
using UTF-8.

The only thing we should teach authors is "Use UTF-8, period."

It’s only implementation that need to worry about @charset, in order to 
not break legacy content that depend on it.

For any change to how an existing feature behaves, we should evaluate 
the risk of the change breaking existing content, including content that 
may rely on broken rules or declarations *not* applying.

I think this change is not worth it.
