My very different impression is that this discussion has gone on for ~8 years now (see e.g. https://www.quantamagazine.org/physicists-debate-future-of-supersymmetry-20121120/ … https://www.quantamagazine.org/physicists-and-philosophers-debate-the-boundaries-of-science-20151216/ … https://www.quantamagazine.org/what-no-new-particles-means-for-physics-20160809/ …) & some high-energy physicists are pursuing new ideas (see @QuantaMagazine) as others change subfields.https://twitter.com/JimBaggott/status/1217011515385139201 …

The main reason SUSY is still researched is because there we can tackle problems like confinement analytically, with hopes it can help in the real world
Maybe not the ‘main’ reason for some people, but that’s what they put on grant applications
