The <base> tag addition has had to be reverted as it broke other parts of
the application (notably lazy loaded tabs like Instance Details), sadly.

Regarding which router to use - I've used the built-in router in the past
quite successfully. I think I'd want to see a solid reason for using a 3rd
party one. It could be that nested routes are part of that, but I kinda see
that as a convenience thing, unless I'm missing something core to how
routing is planned to be done. Then again we really haven't had any
discussion about how we see routing work. The one patch that's up that uses
routing seems perfectly able to do so without needing extended capabilities
of 3rd party routers.
