[Development] Making Binary Incompatible Changes after Qt 6.0

[Allan Sandfeld Jensen]

So, we can:

1. Live with it or find a work around
2. Break BC after 6.0.0 (we have don that before, though only when accidently 
breaking BC in a point release)
3. Break BC again "soonish", like after 6.2 or 6.5

Any other options?

Best regards
