Learning extra syntax is a tax, too. As far as Dave's proposal is
concerned, it seems higher to me, without any added value.

There are substantial differences between legacy modules and what will
be in ES6. People will have to adapt, whatever we do. Drawing the
"people running away screaming" card is unhelpful rhetoric as long as
no valid technical argument is involved. The logical conclusion of
your argument would be to just adopt the union of the existing
systems, so that nobody has to change their habits. There is good
reason why TC39 didn't choose that route.
The more convincing argument would be interop with those legacy
modules. But the magic for that will be in custom loaders, and AFAICS,
the problems (and solutions) will likely be the same in either
