I've started to "standardize" my own use of Markdown as "whatever works in the apps I use". For me these apps are iA Writer, Obsidian, and Astro's rendering pipeline (which uses the Remark/Rehype ecosystem under the hood).

This sucks for sharing documents with other people, but in practice it's not a problem. 99% of my writing never leaves my notes app or blog. And when it does, I often export it to PDF or Word to make it easy for non-techie people to read (I love Pandoc for this, it's easily one of the favorite tools in my daily toolkit).
