Sorry my friend - but embedding static PDFs in Git is my opinion an anti-pattern. The KiCad (or EDA) sources should be the single source of truth, with visuals generated/exported locally when needed.
If you don't like it.. well it's a free world and every engineer has it own preferences :-)
Neglecting a schematic is an anti-pattern. And I never said it had to be PDF. Besides, of all the crap people shove in Git repos, a simple bitmap that compresses well and conveys extremely useful information has to be the least offensive.
Maybe an idea for the next project: setting up a CICD chain which auto-generates them for releases. Will take a piece of your critics with me.
That's an excellent idea!
