Comment (by lightningspirit):

 Although those functions can be used anywhere, in my opinion their purpose
 is to be used in the core mainly.

 {{{__return_false}}}, {{{__return_true}}}, {{{__return_zero}}} and
 {{{__return_empty_array}}} are not so well-known, besides there are no
 codex entry for them...

 If you can pass {{{false}}} to {{{register_post_type}}} *callbacks* and a
 lot of other functions why not here too? It's just to make things easier
 for developers.
