None of the current invocation commands use a prefix argument to control
display, so this would be a departure from established practice. I think the
change you've described is better done locally, for those who want such
behavior.

Another way of doing this that might be nicer would be to check if the
shell-command string ends in "&!" instead of "&", and to take that as an
indication it should be executed both asynchronously and "silently" (without
display).
