It took only 15+ years for the postconf command to be able to warn
about typos in parameter names.
What you are asking for requires knowledge of how every Postfix
program uses its parameters, and doing all this without duplicating
the semantics of those programs, because duplication means that
things will be out-of-sync all the time.
This could be a good opportunity for deep learning.
