warn if apt-key is run unconditionally in maintainerscript
We want to stop hard-depending on gnupg and for this it is essential that apt-key isn't used in any critical execution path, which maintainerscript are. Especially as it is likely that these script call apt-key either only for (potentially now outdated cleanup) or still not use the much simpler trusted.gpg.d infrastructure.
