Just FYI, although the Ubuntu version naming scheme lends itself to being abbreviated to a single letter, this isn't true for Debian: the last three releases were Bookworm, Bullseye, and Buster.
Digital signatures are permissible under the current rules and in principle avoid this issue although the software tooling around it isn't there. Similar example: Debian packages are transmitted over HTTP, but this isn't a problem because they are authenticated with GPG.

The example of the word "German" is amusing because it's kind of coincidental. There used to be more "German countries", and if unification in the 19th century had gone differently, we might still have use of a term for the collective actions of those countries. See for example the Austro-Prussian War, also known as "the German War."
There's an entire meme format to this effect ("R E T V R N", imitating Latin engravings.)
