Is there a way to ensure that a multibound type uses a specific scope and qualifier? That is, if I have

@Multibinds @Singleton @MyQualifier Set<Foo>

, how could I make sure there isn't a binding that's accidentally unqualified or

@ActivityScoped

, and thus be missing from the

@Singleton @MyQualifier

Set I'd be injecting?

You could use Dagger SPI to build validations for this. I wrote about this here. https://arunkumar.dev/dagger-spi-building-custom-validations-for-dependency-graphs/
