Is there any authoritative documentation on R release nicknames?

In response to an email asking if there is a system to the names, Peter Dalgaard states there is

"No system (except that they should be in season at release time)"

Thus, they are not alphabetical or otherwise ordinal -- there is apparently not a way to infer the order of releases from their nicknames.

There is, however, the appearance of a possible general theme:

As no one has uncovered any documentation, I'll tentatively accept my own answer.

Peter Delgaard has confirmed that the release names are taken from the Peanuts comics, in his talk made at useR!2018: https://www.youtube.com/watch?v=z1vTSdRolgI

At about 8 minutes in is when he starts talking about the release names (screenshot from the video):

He also references this site for an explanation of the releases: http://livefreeordichotomize.com/2018/04/23/r-release-names/

I'm surprised @joran didn't follow up on his own hint in the comments section. All of the version names can be traced directly to the Peanuts cartoon. I stumbled upon the evidence in my daily peanuts desktop calendar:
