Don't get me wrong, I'm not saying it's not a defect. Merely suggesting possible workarounds.
Looks like there is some hardcoded stuff in the code that somehow links «information» to «item» (as in InformationItem conveyed)
My guess is that the enable/disable MDG dialog will be removed at some point in the future as it no longer actually disables the MDG (it merely tries to hide it) and the same result can be achieved with perspectives.

Want some more weirdness?
So, as I drag the Item off the toolbox, the Properties window shows <OurProfile>::Item ONLY! It is selected at this stage. Unelect it and reselect it and it has the EPProfile::Inforation stereotype ADDED!
EAUI!!!
What you've said about future plans may well be true, but you CAN'T muck about with users in this way. IIRC either you or qwerty or both physically remove the unwanted MDG files what you are doing is disabling the MDG "with extreme prejudice". So, there is obviously a Use Case that says, regardless of the perspective setting, I don't want the MDG to be activated (for new items). So even when perspectives replace MDG enablement/disablement, you need to be able to say, globally, don't provide this to any perspectives.
Anyway, enough discussion for now. Hopefully, the Sparxians will provide some insight into what is happening (and why).
