This whole discussion is ridiculous. When you customize your vim key bindings, you do so either on your machine, or your profile on some remote server. One does not mess with other&#x27;s computers or settings. But ...<p><i>&gt; Or it&#x27;s based on subjective feelings and cargo cult?</i><p>What if it is? What if I am _factually_ not &quot;more efficient&quot;, what if I am just &quot;happier&quot; with _my_ setup on _my computer_? how does that in reality could have a negative effect on a team? I am of course assuming that the &quot;we mess around with other&#x27;s machines or profiles&quot; is an obvious-enough bad practice that it doesn&#x27;t happen. Right? Right!?
