The advantage of using 'runtimepath' (not 'runtimeparh') is that the
sysadmin and the user can to some extent customize the plugin by
adding their own scripts in other directories than those located under
$VIMRUNTIME (which is reserved for scripts distributed together with
Vim). For instance, if a sysadmin loads a set of scripts for all users
of a given system under $VIM/vimfiles/… a user who knows what (s)he's
doing can customize it by means of additional scripts of the same name
and path below (on Unix) $HOME/.vim/after/… or (on Windows but in Vim
notation) $HOME/vimfiles/after/…
Also, if a third-party plugin (installed under $VIM/vimfiles/… or
$HOME/.vim/… etc.) becomes an "official plugin" distributed with Vim
(as happened in the past for matchit, netrw, VimBall, and others), its
scripts will change location and come under $VIMRUNTIME/… By using
'runtimepath' the plugin will continue functioning in exactly the same
way regardless of under which of the 'runtimepath' directories its
scripts are installed.
Best regards,
Tony.
