Well, I stand corrected regarding the RAE and Rioplatense. By the way, is Rioplatense used widely in Argentina outside of Buenos Aires province?I agree with what you wrote and very much dislike this new ruling too (I think language is a living entity and evolves with use first - just like what we now call Spanish evolved from the way a certain group of people spoke Vulgar Latin, and English evolved from basically a pidgin of Saxon and Old Norman).
However, a common misconception is that the porteño/Rioplatense dialect is not an official, regulated dialect. It -including it’s odd verb forms- is recognized by the Real Academia Española and it has its own associated academy (the Academia Argentina de Letras). When the porteño government (stupidly) talks about “correct Spanish,” they are referring to “correct” Rioplatense Spanish.
As it happens, there was some news regarding the RAE and inclusive language over the weekend: https://www.lanacion.com.ar/cultura...engua-dijo-el-titular-de-la-real-nid20062022/
'“It is society, it is the speakers who decide how their language evolves. They will also decide with inclusive language. The language always changes very slowly,” [the director de la Real Academia Española (RAE), Santiago Muñoz Machado] told the press, according to the newspaper El País and the EFE news agency. The academic indicated that in Spain there is not "the tension that can be seen in some American countries" regarding the use of inclusive language, which, he said, today is "both a linguistic debate and a political debate", since it seeks to "do more visible the issue of women's inequality”'.
Personally, I'm not overjoyed at having to relearn Spanish for the x time (having previously learnt Spanish from Spain, Mexico, Chile, and other places), but I accept that inclusive language is coming, and it will be easier to integrate it in Spanish (a huge number of problem cases can be resolved by exchanging an 'o' for an 'e') than in some other languages.
I do think that the cynical grandstanding by Larreta and his team of mediocrities, in using this topic as a political football, is entirely repulsive. And yes, of course he organized courses for inclusive language, on the city's own website:
