yes, these are all fraught. Any X-to-Y format exchange is a brew/apt miracle in my experience. It's not necessarily important for a LaTeX document to be render-able in all media, but the maths disciplines, for example, should be asking themselves how they want to be able to search for things including formula, algorithms etc, and finding ways to guarantee that a maxima of media support search/find/read operations on their articles. It's not just about how easy is it to input? but it's very similar to "how easy is it to get back out?" it has been a bit of a mismatch in maths re formulae expressions, and how those are represented visually vs. textually.
