Requests for comment/Shadow namespaces

A lot of this depends on the implementation details of global scripts (cf. 39610). However, in either implementation, it would be possible (and advantageous) to have a central repository somewhere.

Scope
For the purposes of this RFC, we're looking at least:


 * Global gadgets (bug 20153)
 * Global Scribunto modules
 * Global templates??? (bug 4547)

commons.wikimedia.org
Outside project scope? Already treated as a central (media) repository with precedence support (where will use the Commons version, unless a local version exists).

wikidata.org
Outside project scope? Also doesn't really exist yet.

meta.wikimedia.org
A number of cross-wiki items already largely lives here (global blocking, global title blacklist, global spam blacklist, global user rights, etc.) - but these are administration rather than content sharing.

mediawiki.org
Suggested at:
 * Thread:Talk:ResourceLoader/V2 testing/Questions about permission model and developer workflow
 * ResourceLoader/Version 2 Design Specification

MediaWiki.org is its own community and its own wiki. It will likely have local needs that could conflict/get in the way of global needs. It probably makes sense to treat mediawikiwiki as a documentation wiki for the MediaWiki software.

scripts.wikimedia.org
Hmmmm. Create a new wiki? Do we want a wiki where it's all (or mostly) developer-types running around? There are a lot of features of using a separate dedicated wiki of some kind for global scripts.

scripts.mediawiki.org
Are we serving Wikimedia wikis or any MediaWiki user? This could always be a redirect as well, of course.
