Would genesis-oik benefit from a theme.json file?

[bobbingwide]

• Several of my block based themes have a theme.json file which supports setting a custom link color as well as a custom text color.
• Several of my blocks support custom link colors. eg sb-children-block ( Improve ability to style the block in the editor and front end sb-children-block#9 ) and sb-post-edit-block ( What's the secret to getting Link Colour to appear?  sb-post-edit-block#4 ).
• Would adding theme.json, with the right content ( settings.color.link: true ) automatically enable the options that these blocks allow?
• What other benefits might we see?
• What about the cons?

Requirements

• add theme.json to the genesis-oik theme

Proposed solution

• start simple and add things as required; copy theme.json from Fizzie - which was based on genesis-a2z / genesis-oik
• test everything works as expected - compare what's on s.b/oikcom with oik-plugins.co.uk
