In that case, I think you are misunderstanding the relevance of Johan's
argument here. Let me try to phrase it differently. Some people who can
reasonably claim to have experience with million-line plus codebases are
warning that this change is too disruptive, and makes maintenance harder than
it ought to be. On the other hand, of the people who say the change is not
really disruptive, none of them have (yet?) made claims to have experience of
the maintenance of extremely large-scale codebases. The authority of the
speaker does matter in technical arguments of this nature: people without the
relevant experience are simply unqualified to make guesses about the impact.
