Paul, I'm not answering for Doug but I didn't read his comment the way you did, he just said that someone mentioned that Phocus does a better job in dealing with shifts than C1 does, and asked whether there was evidence anywhere of this. I honestly didn't read that he was dismissing any problems that Phase cmos owners face, just asking whether there was evidence that Phocus solved the issue for 'blad owners. I think it's a fair question to be honest, if the Hasselblad 50 can shift without issue because Phocus cleans it up then that's a big thing and would be a real advantage for tech cam owners wanting a cmos back who may feel limited by what Phase/C1 can do, nobody knows how the 'blad 100 handles shifts I don't think because I'm not sure anyone has one do they?
I could be wrong of course!

In the forums there are relatively few Hasselblad owners, and even fewer that use it with tech cams. Hasselblad as a company has not been as interested in tech cams as Phase One. As a result, there's less information floating around about how Hasselblad + Phocus deals with tech cams.
When it comes to how well the camera hardware handles shifts its up to the sensor, and if it's the same sensor, handling is the same. So the Hasselblad H6D-100c will handle tech cam lenses just as good (or bad if you ask me) as the IQ3 100. In addition to color casts some sensors produce special artifacts that require the LCC algorithm to be specially adapted for the sensor. The Dalsa CCDs had both tiling and microlens ripple, which meant that a normal LCC algorithm would not clean up the file fully. As far as I know only Lumariver HDR and Capture One can deal with Dalsa CCDs in full, that is if you use H4D-60 (the only Dalsa-based Hassy) I
suppose shifting can be problematic, but I do know that Sean Conboy has used one for architecture photography so it's not impossible. Personally I haven't tried Phocus LCC algorithm with a H4D-60 so I simply don't know how it behaves, and I doubt any user on this forum knows.
Kodak sensors (most Hasselblad's older backs) and Sony sensors (the new CMOS backs) don't have those special artifacts, and thus work with a standard LCC algorithm. Oh well, there's some very low-level ripple in the Sony's but it's not showing for most people and even C1 doesn't fix that, at least not now. There's of course the crosstalk issue with the Sony CMOS, but noone can correct that so that's just something you have to live with.
I do own a Hasselblad back and use it on a tech cam, but it's a Kodak 50MP sensor (unproblematic) so LCC is no problem at all.
Anyway, the problem is that there's limited knowledge about Phocus for tech camera use on this forum while there is huge amount of knowledge for Phase One backs. Does that mean that Hasselblad H6D-100c + Phocus will work worse? No, in all likelihood it will work just as good, but to be sure one needs to find someone that has tested and just as you say, there's noone that has it yet and use it with a tech cam, at least not on this forum.
