Good point about the client-server boundary getting blurred in the app router. The app router generally doesn't feel fully baked yet. I used it for both [Outer Space](https://outer.space) and [Charlotte's Web of Trust](https://www.charlottesweboftrust.com/) and found errors harder to diagnose and the documentation less clear.

It solves some of the pain points of pages but introduces new ones. SN still uses the pages router. We'd probably benefit from switching though.
