Sorry @NicoletaPopoviciu , overlooked this while reviewing. I think yes to this change, then we'll want some targeted changes similar to it, but slightly different, for release/1.4.x and release/1.1.x (docs for those should not say "1.27-1.30" since LTS versions don't typically remove old support, just add new). The Jira ticket has a few notes on those versions, but happy to discuss as well.
