It seems that the title of [[MediaWiki:All messages]]
is misleading,
because it actually displays only the messages used by the software, not
those inserted by users. (And, quite frankly, I don't think it should;
[[Wikipedia:MediaWiki custom messages]] is already a huge mess, and
desperately needs splitting up.)
A Special page would either
(1) have a hardcoded list of messages to display (which would then need
to be updated whenever a new message is introduced into the
software; admittedly, this would be easier than updating
[[MediaWiki:All messages]]; or
(2) display *everything* in the MediaWiki namespace, which (as described
above) would be horrendous.
Actually, I was thinking you would basically port the alogrithm used in
'InitialiseMessages.inc' to contruct 'All_messages', which is to walk
'$wgAllMessagesEn' and/or the appropriate language array, and catch the
array value and the current database value.
So, only values in the language array would be shown.
