To some degree this is true but I am not sure that you can have optimum
spacing for that big of a frequency range and still maintain a constant
impedance. It would be nice to see a model.

As pointed out by W4TV when you can vary the element lengths the spacing
is less of a concern. The boom is the limiting factor and this is true
with any multiband antenna.

One other 'con' that does  not seem to be mentioned yet:

The element spacing is a compromise on ALL bands, so gain and f/r will be
less than optimum on any band.
