There should be additional options for linking

Good example of graphic solution is used in wordpress.

This form is missing only rel=noopener and rel=nooreferer. This feature would improve usage of ghost blog in SEO perspective.

You could build this out with internal tags that apply those attributes in your theme. It would take some work, but if you absolutely need it and can’t wait on Ghost - thats an option.

Those tags are just an endless hole, so I don’t think Ghost will move on it. Since that image is forgetting the ugc one for user generated content. Ghost can’t even think about applying that since comments are so different between themes. Not to mention, the complexity for this is large - the handlebars themes output URLs, not fully built HTML for href. So the breaking changes to support these endless properties in a way that themes can use them is far too complex.
