OSGi allows you to publish a service with multiple interfaces, but the
properties then apply to all of them. DM follows that model, so what you’re
seeing makes sense from that point of view. If you want different properties,
you have to define multiple DM “components” (which can all use the same
instance if that’s what you want).

You might have hit “send” too soon… You cannot depend on something that is not
a service. You can have a component that does not publish a service but does
have dependencies on other services.
Well, the only thing you could do is implement some custom form of dependency,
but that would then have to lookup components in a registry. Which almost
sounds like another service registry. :)
