Yes. I mentioned that under workarounds.
But it reduces readability — a core reason for using Markdown in the first place — and portability as well.
Edit: In general, it seems to me that the departure from the core Markdown syntax should be the exception; if it interferes with readability, it should be optional.
And I say that as an avid user of MultiMarkdown, which has a lot of features not included in Obsidian-flavored markdown.
