Gutenberg phase 2 development is underway and one of the first orders of business is porting all existing core widgets to blocks. This task is one of the nine projects that Matt Mullenweg outlined for 2019, along with upgrading the widgets-editing areas in wp-admin/widgets.php and adding support for blocks in the Customizer.
Contributors on phase 2 are also developing a Classic Widget, which would function as a sort of “legacy widget block” for third-party widgets that haven’t yet been converted to blocks. There may be many instances where plugin developers have not updated their widgets for Gutenberg and in these cases their plugins would be unusable in the new interface without the option of a Classic Widget. This block is still in the design stage.
The widgets.php admin page will need to be completely reimagined as part of this process.
Updating the widgets management page and bringing blocks into the Customizer is a major overhaul but will further unify WordPress’ interface for editing and previewing content. Widgets have served WordPress well over the years, making it easy for users to customize their websites without having to know how to code.
