That's perfectly fine. Copperspice didn't aimed to support legacy code, and thus could introduce backwards incompatible changes without looking back.

Dropping support for legacy Qt code also ensured it was automatically irrelevant, which is why most people in a thread over Qt have absolutely no idea what copperspice is, let alone that it existed for over a decade.
