Comment (by Mamaduka):

 @scruffian, the core data or presets are available for classic and block
 themes. I just tested this with the Twenty Ten theme and added the
 following code to the `wp-includes/theme.json` style config.



 {{{

 "blocks": {
         "core/button": {
                 "color": {
                         "text": "#ffffff",
                         "background": "#9b51e0"
                 },
                 "spacing": {
                         "padding": "calc(0.667em + 2px) calc(1.333em +
 2px)"
                 }
         }
 },
 }}}
