Hi @rolfedh It is a massive and tricky project, thanks, I've started making suggestions, but then stopped as I thought #ifdef extension allows a given extension and #ifndef disallows it, or is it the other way around in the Doc context ?

Understandable confusion. It's slightly counterintuitive.
The ifndef blocks display content in the community docs and hide it in the product docs.
I've provided the reason for this approach here: #39999 (comment)
