Remapping default key commands is a fraught problem. Doing so acclimates the user to a custom environment which is not strictly a superset of the default environment. This makes it very difficult to switch to other environments and remain productive.
Personally as a developer (not a sysadmin), I choose to be more productive 99% of the time than eschew customizations because I might vim in remotely here and there.
Defaults enjoy privileged status.
