Having a common standard would be great indeed, but I am afraid every 
CLI will always have its own specifics way of displaying things - so the 
hard part
is to make sure every tool out there provide a way to get that specific 
output wether it's via a CLI option or via code (like the flake8 plugins)

You've just described what flake8 is trying to achieve: being a dummy 
runner on the top of a bunch of tools  :)

but in order to perform this in a smart way, it needs to add a bit of 
glue to reorder the outputs etc.
It also provides a standard/stable interface for the user and other tools

So at the end, adding a new metrics can consist of simply creating a new 
flake8 plugin and
let flake8 take care of the CLI + configuration part.
