I have seen rather convoluted codebases where the actual invocation line 
is hidden in a complex bash script called by make, called by another 
bash script, etc. It's not necessarily good but things like this are 
reality.

Having an fast, easy reliable way to get full repro is invaluable in 
such cases.
