I totally agree, and as I mentioned, configuration compatibility was NOT a selling point at all - I just mentioned it as a property of shinken that makes it (supposedly) a drop-in nagios replacement without even the need to reconfigure.
I see that as a selling point for testing (not relevant to me because I didn't have a previous nagios installation) - to test shinken for real, you just install it (a couple of apt-gets) and run it - you don't need to configure it.
Once you've actually decided to commit to a new system, configuration compatibility with your old system is much less important, of course (provided it's not a tangled mess of 1000 hand edited files)
I'm pretty sure everyone cares about plugin compatibility, and a few people are impressed by the finesse involved in bringing configuration compatibility.
Your point about the ease of compatibility testing is quite salient.
