Legacy widgets in Twenty Twenty-Three theme?

Hi,

Been playing with the various IndieWeb and syndication features for WordPress today.

I see there are options for 3 legacy widgets, that are not supported in the Twenty Twenty-Three theme anymore:

• widget_relme_widget
• widget_hcard_widget
• widget_widget_original_of

Will they be converted to blocks?

Thx!

Sincerely
DJM
