I've just published an initial sketch of a library called bitflags-derive that takes advantage of the Flags trait to support flags-aware custom derives. This should be a good way for us to add support for external libraries in your bitflags! invocations going forwards.

So far I've just added support for deriving Debug to get a bit of infrastructure in place, but would love to add support for other libraries there too, like binrw for example, which we couldn't add due to it being unstable in #370. If there are any you would find particularly useful, please feel free to raise an issue over in bitflags-derive and/or PR support for it. We'll use optional features in bitflags-derive to toggle other libraries on and off.
