I know you're not allowed to do that, but there's no technical reason why that 
is so. Unlike binary compatibility. It's a choice.

But contrast that to the distros asking for the renaming and the majority of 
Qt developers rejecting that. The ideal solution for either group was rejected 
outright as soon as the discussion began. So we had to come up with 
alternatives and compromises.
