You could make several arguments here, but they're all small until you aggregate them.
1) Breaking working systems should be dissuaded, especially when it comes to human interaction. There's a reason that Microsoft still has a start menu and "File/Edit" menu's
2) There is a certain level of arrogance to the notion that a developer of core infrastructure for literally millions of users can just change things and expect everyone to fall in line without giving credible reason for people to do that.
3) Adding an additional tool to everyones cognitive load should be done with care and delicacy, as it stood there was one set of tools for _all_ file accesses, and there is now a new one.
PS; on a personal note, I'm glad I do not work with you, I find your attitude in the grandparent comment deplorable.
