Without taking a stance one way or the other: is there anything
basically wrong with fundamentally changing the way we work if doing so
allows us to tackle a problem in the best possible way?

I think Godwin's point was that due to how our filesystem is
well-organized (i.e., architecture-independent stuff in one bunch of
directories and architecture-dependent stuff in another), it's fairly
easily possible to fix that issue, which basically makes it a non-issue.
