A wise elder once advised me that if I learned to work quickly and comfortably with an application’s defaults, I would be just as quick and comfortable on any system I would likely encounter. Very zen. Great advice.
Seems like using a tool to its fullest potential to get more work done is better advice.

How often are we encountering other systems…? And even where I am rarely ssh'd into something else … are we doing so much editing of code (live in production…?) that it matters? (I heavily customize my vim, but it isn't like I'm lost on a remote system with stock vim, or nano. ed is another matter.)
But if I need tons and tons of editing, … sshfs+local vim/terminal? But this just such a rare case, it seems like one of those "we should optimize for the common case" — which this is not.
For me personally it's a classic old timer habit from the days when you had to be prepared to fix a system using only the tools in /sbin. That doesn't mean you should operate like that all the time, but you should certainly know how to do so and be comfortable doing it.
