a few losses will be in every transition - but one may change the losses into wins - for me that means that i dropped multi-arch, use the new beta beyond compare (amd64) instead of i386, lost teamviewer which can run in a Windows VM and be done with it - ymmv. The problem with the transition is, that not only some programs and libraries will be recompiled - some projects and maintainers use the transition to get current code into debian, which make sense. But new programs and libraries can introduce a lot of new bugs ...
