I guess it depends on what you mean by "incompatibilities".

If you start switching between branches like that then, obviously, the
binaries that you create are liable to contain a mismatch of things and
might not be entirely compatible with any of the branches.  For example,
if I check out the dev tree, build glibc from that, then switch to
stable and start trying to build some other packages then I will
probably end up with a dependency on a version of glibc that doesn't
exist in stable.  But this has always been the case and the answer is
simply "don't do that, then".

So, in summary, I don't think there's any new issue here and it doesn't
really seem that any particular action is required to address it.
