[ I'm probably responsible in large part for the recent popularity of
  the #' notation, so I figured I should chime in:  ]

While I generally prefer to use #' where applicable, I have resisted the
temptation to use it in keymaps because I have found it leads to
"spurious" warnings more often than in other contexts (and the impact
of an invalid binding is also less serious than a call to
a non-existing function).

Also, to me #'f means "the function bound to this symbol" whereas 'f
means "the symbol f", and in key-bindings I really want to use "the
symbol" rather than "the associated function" because `C-h m` gives poor
results when keys are bound to lambda expressions.  It's a rather
"philosophical" argument, tho.
