It's nice that Comonicon automatically adds support for --version, but the "short flag" is not what I expected. I think -V is slightly non-standard, or at least much rarer than -v for --version, e.g.

~$ firefox -v
Mozilla Firefox 102.0.1
~$ plasmashell -v
plasmashell 5.25.2
~$ julia -v
julia version 1.7.3
~$ zotero -v
Zotero Zotero 6.0.4

Some commands do seem to grab -v (e.g. bash, cat, and others), however they tend to only offer --version and not use -V as a substitute.

With this all in mind, I think it might be more intuitive if Comonicon always offered --version, and then adds -v (not -V) automatically when it hasn't already been assigned to something else. Does this sound possible?
