Maybe he meant something like:

or

And as you can see, not more polygons, but actually less.
as a rule of tumb, "less points implies less polys".
NOTE: both examples could be even more simplified (less points) if we removed
the disc center point.

Not a Rule, just a "guideline", authors are NOT obliged, but they are
encouraged to do it, because it's better.
And as you can see from my drawings it's NOT difficult to avoid. At least I
don't think so.

By what I have said above, NO drawback, or lack of versatility.
When Authors/Users start to see the benefits they will strive for better parts,
with such a tiny extra effort.
See ya
