Not sure if this rhetorical, but I'd be happy to chat strategy. I suspect your best bet would be to a tool that shows the value of dependent types quickly. What is the biggest benefit in having them, and how does the tool/lang show that. Lots to explore from there.

I think lots of the initial value will come in type-directed meta programming. Lots of examples from Haskell and Rust and C++ that seem awkward and hacky are nice and beautiful with DTs.

There may definitely be benefit here, but IME it's a minority that gravitate towards heavy use of macros/templates. You may end up optimising towards a relatively small crowd of developers. Are there non-meta programming examples where DT flourish?

Yeah, that's a good point. It more shows up down the line in the quality of the libraries. Like, Diesel (for Rust) would be much nicer with first class types and types that depend on values. Will have to think on this! 🤔
