Neither the Emacs manual nor the Elisp manual documents all
commands, let alone all functions, that are useful.  (And
libraries are typically not mentioned as such.)

It's always a judgment call what to put in a manual, but there
will always be tons of functions and variables that cannot
(and in most cases should not) be documented in the manuals.

This one is essentially a utility function.  If it were
autoloaded then it would be relatively easy to discover using
completion: `C-h f string TAB'.  (And if you have a better
completion system you can also use `C-h f trim TAB'.)

If you think that a particular thing (e.g. function) should
be documented in the manual, the way to get your voice heard
is to file a bug report (aka enhancement request):
`M-x report-emacs-bug'.  Likewise, if you would like to suggest
that such a function be autoloaded.
