For what it's worth, I finally got around to making a plugin that I've been using to add notes to collections & folders fit for public consumption. Not photos, just yet, it's on the todo list.
Essentially it allows you to create and view markdown notes to the current active source (selected collection or folder).
Briefe explanation at https://buggeringabout.com/daisynotes-for-lightroom/ along with a link to the download.
If someone can confirm it's all working I'd appreciate it and I hope it's of some use.
