Of course I am, but I don't know why you're saying so.  Compilation-mode was 
obviously designed to be a general facility, thus the great flexiblity in the 
regexp alists and compilation-search-path, etc., so the original designer knew 
their ability to envision the details of future use cases was limited. I'm 
suggesting a feature that makes it more adaptable to un-envisioned use cases.
