In reply to Tomas M..

This WP.org behavior can have positive effect – people will be so unsatisfied, they will create new joint project on Github (perhaps backed with Kickstarter campaign) to replace the current admin interface or parts of it.

This way WP Admin will be just another fronted for the WP Core engine, it also opens opportunities for strong commercial products.

Core getting matured to be there actually. Once the WP-REST-API delivered the baseline properly, anyone can build their 'Admin Panels' as they see fit.

Looking into 2016, guess there will be many awesome custom-made Admin panels, if not sooner! :)
