The caveat here is that we'd lose the "inline" glimmer features, like what is demostrated here

Discussion on the future: https://github.com/orgs/unifiedjs/discussions/213

• additionally: https://github.com/orgs/unifiedjs/discussions/214

And separate repo to implement ideas: https://github.com/nullvoxpopuli/glimdown

The solution is going to be a custom parser that hopefully uses @glimmer/parser, and converts the AST to UAST or whatever it's called -- or at least uses the format.

(not that this project uses Docfy, but we're solving similar things -- Limber: at runtime, Docfy: at build time)

This has been implemented, and will eventually make its way into either ember-repl or another library
