As someone who is interest in getting almost full control of expansion
(with expected consequences) and focusing on other
interpreter/compiler details than implement various expanders, I'm
still quite interest in old and well known 'define-macro'.

Is there anyone interest in such feature? I'm I able to propose it and
what prerequisites I should meet?

Best.
