But Capture One is not a photo editor like the others you mention, but a Raw converter. Again, it would be nice if C1 could open anything thrown at it, but it's not their main focus, Rawconversion is. A photoeditor obviously needs to cater to another audience, not necessarily for Raw files.
I agree, the round tripping (if needed, and it occasionally is) is what also puts some pressure on C1 to facilitate it, or offer better solutions from within C1 itself. But that doesn't mean that other applications shouldn't do their homework as well.

CO is no longer solely a Raw converter. It's added DAM features, a managed catalog, and offers round trip editing. I can understand PO's position that they don't want to support PSDs (while I don't think it's wise), but I do expect near universal support for TIFF. It continues to be my opinion that if CO wants to be a serious option for Aperture users, and an industry alternative to Lightroom, it has to up its game. Excusing PO as "small" and CO as a "RAW converter" doesn't put much customer pressure on them to improve.
Perhaps PO does not want to compete in that way. That's their choice, of course. But I, at least, am hoping for a real challenger to Lightroom and CO is getting very, very close. Fix some bugs, clean up a few features, add real image stacks, and they will be near about there, in my estimation.
