To turn your browser (an agent acting on your behalf) into a proprietary application (an agent acting on behalf of a website) -- i.e. the equivalent of forcing you to install a proprietary application in order to visit a website.

If websites wanted this feature, and the choice is between Chrome implementing it versus me installing proprietary software, I would rather choose Chrome, especially since Chrome is implementing it in the open.

There are already various services that require proprietary applications to be installed, most of which are closed-source with dubious security track record. Replacing those propriety apps with a common web browser is not necessarily a bad outcome.

Personally I am voting with my money and just avoid services that are user-hostile, independent of which user-agent I use to access those services.
