It depends on your attitude to risk doesn't it. I disabled it for a couple of reasons, first that was the way it was to begin with and second because LMDE is my main (though not only) distro, so I don't want to upset it with unstable packages, which is what romeo is supposed to contain. If it wasn't my main distro I would probably keep it enabled.
Only you can decide.
