Those comment templates are actually really well structured you've invented a mini decision record format without calling it that.
The problem you're hitting is discoverability the why is there, but only if you happen to read that exact line. What if a new dev could ask 'why does this auth flow work this way?' and your comment was part of the synthesized answer along with the PR, the Slack thread, and the ticket that created it?
