Shell Relative Routes Documentation Incorrect?

[BurningLights]

Description

According to the docs at https://learn.microsoft.com/en-us/dotnet/maui/fundamentals/shell/navigation?view=net-maui-8.0#relative-routes, shell routes with different numbers of slashes should do different things. However, reading and stepping through the navigation code, I can't actually identify any general difference between the two types of relative routes and the two types of absolute routes. Routes with no slash and a single leading slash seem to behave the same, and routes with two and three leading slashes seem to behave the same.

The only spot I can identify where no slashes vs one slash or two slashes vs three slashes would make a difference is in this line: https://github.com/dotnet/maui/blob/61e984eb01fa8fa7fd7133a68bd76008865a01a0/src/Controls/src/Core/Shell/ShellUriHandler.cs#L318. It compares the original route request against the registered route strings. However, any arbitrary character would make a difference there. It seems going back to the original Xamarin Forms spec for shell routes, there was a plan for each number of slashes, which is reflected in the docs. But, is it possible that the implementation actually ended up only differentiating between absolute and relative routes, rather than having two types of each?

I think we should just replace this entire section with a warning

• Only Pages defined with RegisterRoute can be pushed onto the navigation stack using relative routing
• Relative Routing does not work with anything that's defined inside the Shell structure
• Absolute routing currently does not work with anything registered using RegisterRoute
