Almost all the examples provided as "pretty normal cases" of having overlapping path registrations are already handled without panicking by the path precedence rules. All the cases where you have a wildcard path + handlers for specific variants of the wildcard values, are handled as expected without panics. Only the rather extreme corner case of having two wildcard paths, with wildcards in different locations, but still matching the same path, results in a panic. Honestly if you're running into the second case above, I would question the wiseness of whatever it is you're attempting to do, because reasoning about the behaviour is unlikely to be clear and obvious if registration order is the only differentiator.
