I dont think sharing URLs with state is that relevant anymore. If I want to share something I am looking at that has state dependencies, I take a screenshot. I dont, or ever, expected the ability of a URL to take someone anywhere but the home page or top level sub-directory

If I refresh the page and my state is lost, that is expected behavior to me.

If I do not like the state of the page, I can refresh the page and start over.

It is frustrating when I refresh the page and literally nothing happens, and now I need to go into the URL and delete a bunch of shit in order to refresh my state.

It is WAY more important to me to be able to quickly build any state from scratch. I do not ever want to be 10 minutes into building some specific state on your website. I do not care how well you handle it because I dont trust it to persist anyway. I do not want to trust it to persist.

Focus your energy on improving the navigation of your site or build state into the site itself. Let me save search criteria terms into a named list associated with my account if it's important. I want to be dependent on the URL for as little as possible, even indirectly.
