    Well, I don't care much myself. I have no use for that capability, even
    though this was interesting to implement. So it only depends if someone
    relies on this or not.

    A few months ago I asked on the list if XIP was still useful, and Tim
    Bird replied that Sony was indeed using it. So if this is not too hard
    to keep this feature alive then I'd go with that option.
