We should not move the buttons/links to the right side, or at least not without A/B or usability testing verifying that it doesn't make it less discoverable. (Regardless of whether we have the icon or text.)
The links used to be on the right side until 2013, when I implemented the change that moved them next to headings (T43729). This was motivated by local gadgets on most large wikis displaying them this way already for years (but not enwiki) and ancient usability testing from 2009 (https://meta.wikimedia.org/wiki/Research:Section_edit_modification; F117849). More documentation about this change exists at https://meta.wikimedia.org/wiki/Change_to_section_edit_links.
