This makes sense to me now. I get what you are saying. The gpg binary installed on my system is fairly new:

I'm not sure if that has anything to do with it. I'm going to have to investigate further to figure out what is being executed and with what parameters that leads to the prerefences prompt. While working with GPG on another project I noticed that GPG doesn't like to work with keyrings other than the default ones. I tried a bunch of different combinations of --no-default-keyrings, --homedir, --default-key, etc to try to get GPG to never touch ~/.gnupg and I couldn't figure it out. It would always re-create ~/.gnupg and default keyrings and even read gpg.conf when explicitly told not to. I suspect that is what is going on here.
