Please note we *can* have a binary-incompatible, source-compatible version, 
technically speaking. We do have two version numbers in our binaries:

 libQt6Core.so.6

The first 6 is the source version; the second one is the binary version.

How to communicate the difference to users, how to market the versions, and 
whether it is worth the hassle are completely separate topics.
