yeah, nostrmarkup is much better than ndown 100%, but i like #nup because it's ironic in the same way that nostr is like no-stir

but i think your approach is better, asciidoc is more flexible, i think that what make it get more wings is to simply define a minimal spec that covers most people's needs, and then define that in a document that you make easily available to users to learn how to write it. they will write compliant asciidoc then, but don't need to know the deep features of it, while allowing them to go deeper if they want to.
