> 2. Turing complete macros (not just syntax-case)

I assume, you mean `syntax-rules` here.

If I understand correctly, it's pretty easy to simulate a paper tape with `syntax-rules` macro - that is `syntax-rules` macros are already "Turing complete".

But ... I know what you mean - in practise `syntax-case` or `syntax-parse` would be lovely to have.
