even many of the very widely used LaTex "editors" do have some semi live "preview" feature which often allow some WYSIWYG like features in the preview

similar if someone random non technical person just needs to write idk. 5 paragraphs of text with a head line, no high requirements for formatting, no kind of templates, no anything fancy why would you force them to not have WYSIWYG if that is the perfekt fit for their use case in every single aspect?

Similar markdown doesn't scale to a lot of writing requirements, like _AT ALL_. I know because I have written pretty much any thesis or larger reports etc. during my studies in markdown. And I had to step out of markdown all the time. Weather that is by using inline latex, or by tweaking markdown to PDF conversion templates (by interleaving non mark down sources with markdown by splitting the markdown into many different files and folders which each could be markdown or anything else, and/or inline latex to include non markdown sources imported into latex) etc. It was a nice pipeline, but it also wasn't really markdown anymore, but instead some amalgamation of markdown LaTex and other things. As a programmer that was fine, but that doesn't scale at all to the "standard" user of office applications.
