Fixed Issues (if relevant)

Manual testing scenarios (*)

I'll update these steps with more concrete things, not much time at the moment to put a lot more info here, will try this weekend if I find more time

1. Have a module installed in app/code which uses PHP 7.4 specific syntax which doesn't work on PHP 7.3
2. Run bin/magento using PHP 7.3

Expected

1. Exit code other then 0
2. Explanation of the error

Actual

1. Exit code other then 0 => correct!
2. Just silence, nothing else, this makes it extremely confusing why the command doesn't seem to do anything
