Modes in which direct editing of text isn't sensical generally initialize in motion or emacs state.  This means that the evil-normal-state-map is inactive.  But there are some useful Evil commands in evil-normal-state-map that don't involve editing text, such as:
  evil-record-macro
  what-cursor-position
  find-file-at-point
  evil-quit
and several others.

These are unavailable in for example Buffer Menu, even though they would make sense there.

What's the reason behind putting non editing commands in evil-normal-state-map?
