Well yes and no. Whilst editors, viewers, etc. can be expanded to cover
the entire Unicode range, no one font will cover the entire spectrum. At
the same time, most keyboards are only ever going to have ~100 keys. So
whilst for the main language of a document Unicode makes sense, saying
that you have to find the correct Unicode code point for everything is
not so convenient. (One can arrange different key binds to flip between
which could be used to do for example the math-mode bold A business, but
that may or may not be easier than just typing \mathbf{A} or whatever,
depending on the use case.)
