This is an impressive piece of work. However my use case for bash is simple, concise and portable scripts.

I don't look forward to encountering (read trying to fix) this in production.

Keyword for me is portable. The reason I (and I assume most people) use bash is that it's ubiquitous. This framework wouldn't be. Not that it's not impressive and looks fun to try out. But I can't see a lot of use for it in practical terms.
