Update: We discussed this in the Community Council meeting today, and the idea is to (1) post meeting summaries in the forum for easier digestion; (2) keep the most recent raw meeting notes in an Etherpad pad; and (3) older notes are migrated into a GitLab repository for long-term archiving.
To me this sounds like an acceptable arrangement with accessibility for recent notes while taking advantage of the power of Git for storing older notes.
