This is not fully correct.
This would make it easier to create mobile versions of a website. As a developer, it is easier for me to decide by domain which version should i show. And i can give the user a chance to decide if he wants to see the mobile or desktop version. If i use media queries the user has no decision. If i use a second page tree, i have more editorial work.
I know this would generate a duplicated content problem, but for complex website construcs there are more positive arguments for this feature, than negative arguments i think.
