To the certain extent, yes, it makes sense. This trouble is rather small compared to benefits. I'm in constant search for the perfect editor, but every editor has its quirks, and of course, most editors require learning.

As for the controls that contradict with the rest of the software, there's no trouble for me at all. I don't suddenly start pressing :wq in the browser. As a simple example, consider people like me, who use two keyboard layouts: one for their native language and the other one for English. Even punctuation marks are on the different keys, but I don't have trouble typing the correct ones depending on the current layout.
