Add Layouts back to K2 as an Extension?

Recently, Layouts were removed from Karoo2, they're done automatically when building or modifying a Profile page. As you can see here, in a link to a Support request, it's not a move forward. Can it be rectified with an Extension? If K3 still has Layouts, it might not be worthwhile.
