Sure, it has second order benefits: it makes a few things a little
easier. For example if you want to remove the address to diff the output
of multiple runs, you can just pipe through sed; you are already piping
to get the diff anyway.

But the problems it causes, not being able to identify the source of a
warning, are first order.

Even in the CLI tool, this change is harmful as soon as there are
multiple instances of the same component, like two scale filters.

Detecting that situation to enable the flag would not be worth the
effort and would clash with the principle of least surprise.

Stop with the sunk costs, just drop this misfeature.
