Due to the support issue, no provider in their right mind is going to
share addresses across multiple customers.
Apparently, when it comes to support issue, the question remains one of
degree. And I disagree sharply with you as to the effect on the equation
the use of 1918 brings.

Or providers will use GUA regardless of the /10. Or providers will pool
a collection together. Or providers will go ahead and use space that
already exists, either their own or rfc1918 or even 240/4.
Even if they do not find those options as attractive as this /10.
