As a side note, it would be fun if the "Special:MyLanguage/" extension could also work as the source of transclusion, so instead of writing
[[m:Special:MyLanguage/Tech/News/2014/07|{{subst:#ifexist: Translations:Tech/News/2014/07/Page display title/{{uselang}}|{{TNT|Translations:Tech/News/2014/07/Page display title|uselang={{uselang}}}}|Tech News: 2014-W07}}]]
We could use more directly:
[[Special:MyLanguage/Tech/News/2014/07|{{Special:MyLanguage/ Translations:Tech/News/2014/07/Page display title}}]]
This could require change in MetaWiki's support of transclusion so that it can expand also the content of a special page. For now an attempt to transclude a special page only returns a link to its given page name. There may be issues to allow this because some special pages are very costly (or there could be privacy issues when transcluding some special pages performing special actions).
But a whitelist could be used in the MediaWiki support of transclusion to allow it to expand the contents of "Special:MyLanguage/*" but not "Special:Preferences" for example.
----
However if the "Special:MyLanguage/" prefix can work to create target links on Meta (or on another wiki) by using it after an interwiki prefix ("m:" here for Meta), this does not work with template translcusions for now! You still cannot transclude locally the content of a page located on another wiki: transclusion only works locally. So the following does not work because of this "m:" prefix in the source of transclusion:
[[m,Special:MyLanguage/Tech/News/2014/07|{{m:Special:MyLanguage/ Translations:Tech/News/2014/07/Page display title}}]]
This will only work via a long-waited new feature to support interwiki transclusion with some mecanism (where the full expansion, and wiki parsing will actually be performed by the target wiki (not locally), whuch will be intructed to convert its local links using an additional interwiki prefix given by the source wiki (like what is done in the "File:" namespace for expanding the description pages located on Commons: the expansion of the description page is performed by Commons, which inserts the additional "commons:" interwiki prefix to the links rendered in the description page, as instructed by the remote wiki requesting this expansion).
