For me, the Hunqapillar diagatube was a visual draw-- I liked it better than the parallel-to-top-tube bar of the Bombadil.
The diagatube reminds me of the original Joe Breeze mountain bike frame: https://mmbhof.org/portfolio/first-fat-tire-bike-with-a-new-frame-and-all-new-parts/ Additional tubes have been around for a long time in bicycle history, some for functional reasons and others for style.
