I'm adding onto this: I think that the whole SPA concept is wrong most of the time. You want most of the time some sort of state persistence in the url, so that you can bookmark/pass around something that is meaningful, not something that is always the starting point of everything.

If I'm seeing a list of todos and I've filter actives there's really no benefit into not having the filters reflected in the url. The same goes if I'm navigating some data in the form of some table and I'm, let's say, at page 2.
