There's never a final word on one's choice of software.
And you know what I say about DAM being a life of serial monogamy.....
PhaseOne would be crazy to limit the type of files that can be catalogued. I think it's a possibility - in the exchanges I've had with them, they seemed to think that if you couldn't see a thumbnail/preview of a file then it was pointless getting it in iView. I had to point out that even if you could only see a system icon, you could still manage and find the file. But it's always harder to take features away, and I know others have received feedback indicating they would continue to serve iView's existing market. Whether that same loyal user base is still there, who knows?
