Code review comment for lp:~thomas-voss/dbus-cpp/enable-dual-landings

Ok, looks good now, just one really minor inline comment below. Of course the same thing remains: we need some abi compliance checking implemented when symbols files removal. This would need a bug assigned to someone before we can land that. ABI compliance will be even more important soon as we are starting to migrate things from universe to main for ubuntu-touch, and a library without symbol files is unlikely to go through the MIR process smoothly.

That being said, if my comments will be addressed (the inline one and the bug about ABI-checking), this merge is good to go.
