Many tech blog posts show that Chrome extensions are not available on Chrome for Android, and therefore show how to install another Chromium-based browser on Android smartphones, that support extensions.
Question: Where is an official source about the fact extensions are not supported with Chrome for Android and/or a roadmap about future evolutions (is an estimate date already known about Chrome extensions support in Chrome for Andrdoid)?
(This information is not easily findable on internet; if it is, it is lost in the middle of many articles about how to install other browsers that support extensions, etc.)
