As an avid Emacs user and having debugged unintended side-effects in minor-modes[1] I definitely know that this is possible there. At the same time though I would hope we learn from what works and doesn't work in Emacs and apply it to new tools. I think one of the big challenges will be establishing the best practices for plug-ins to avoid user-experience-ruining clashes.

Thankfully the Emacs community is populated by people who provide excellent bug reports!
