Are covered: yes.  Are easily covered: no.  If you take the tool-bar, 
everything it offers is (very!) easily covered by other means.  Yet it 
exists, because it makes these things easier for some users.

Yes, these tools exist.  Yet I'd bet that many users would find a 
multi-file buffer far easier to use than these tools.  Many users find it 
easier to use customize than to type Emacs LISP code by hand in their 
.emacs file.
