Doesn't this also introduce a combinatorial problem too? If a module
like Asyn needed to alter its behaviour slightly based on the runtime
version of libCom that it's running against, wouldn't some modules
dependent on Asyn also have to do something similar? Programming is hard
enough for most people without having to add this level of complexity to
the development process.

Is there something in PSI's production environment that is pushing you
in this direction instead of accepting that you just need to rebuild
everything downstream of an update? I would recommend taking a look at
Sumo from HZB (BESSY-2) which automates all the necessary rebuilds.
