Sounds interesting: a searchable, p2p no-script-web, based on a subset of markdown https://github.com/runvnc/noscriptweb/blob/master/README.md

I think you could still allow for some react component system (with extra markdown commands) without causing the thing to be turing complete

And there could be an approved set of non turing complete components that gets larger as the community develops it over time.
