I’ve seen it used, but I’m not sure the usage were good usecase examples. Do you have examples of idiomatic usages of Guice Mapbinder? (Cases where Mapbinder is really the correct tool to solve a problem)

Offhand, it looks like a reasonable way to create a registry of runtime-named implementations of a common interface. Consider selecting one of many plugins/modes/whatever from a command line or configuration file: the desired injection can’t be known at compile time. A MapBinder provides an easy runtime lookup without resorting to type-switching.
