Muxes are not composable

[empijei]

A nice feature of http.Mux is that it can be used as a handler, so users can set up separate parts of an application on separate muxes that share a common configuration (e.g. a set of interceptors) and then install them on the root mux.

This is currently not possible with GSW, and we should seriously consider doing it.

To clarify, you are not referring to the safehttp.ServeMux being composable with http.Mux, but with itself, i.e.:

var m1 safehttp.ServeMux
var m2 safehttp.ServeMux

var rootMux safehttp.ServeMux
// These two lines below would not compile.
rootMux.Handle(..., m1)
rootMux.Handle(..., m2)

Correct?

Correct.
