The first release candidate of PROJ 7.2.0 has been released, it does not bump the SONAME so a transition won't be required.
Breakage of rdeps is possible though. pyproj for example tends suffer test failures with newer PROJ releases. A subset of packages will be tested with the new releases once it's available in experimental. There won't be a full round of rebuilds.
