Yes, but the burden of proof always lies with those who want to change
stuff. I've got the easy job here: I just get to say 'look, if you want
to change everything, provide some concrete evidence:
a) that there's a problem
b) that the changes will solve it
c) that they won't create larger problems than the ones they solve'
That's always how it works. You have to provide a justification for
change. No justification is really needed for no-change.
