A few days ago, @Ladsgroup created a very important proposal, in my opinion: Proposal for changing logo of MediaWiki, 2020. It seems to me that we need to approach this more systematically and solve common branding problems:
Perhaps we should ask the community or create additional pages for the overall movement of change. For my part, I can say that this must be done. The design of the main elements of MediaWiki has not been updated since 2003. And no one was involved in positioning the project. Moreover, as it turns out, old MediaWiki logo is a failed proposal for a Wikipedia logo that never had any meaning for MediaWiki.
