Should the Config and GlobalConfig classes and the associated RequestContext methods be reverted from 1.23 as an incomplete feature? As far as I can tell, it is not yet used anywhere, so reverting it should be easy.
getConfig() was added to IContextSource in 101a2a160b05[1]. Then the method was changed to return a new class of object (Config) instead of a SiteConfiguration object in fbfe789b987b[2]; however, the Config class faces significant changes in I5a5857fc[3].
