Yes, it is a practical issue. Please don't assume a use case is
invalid if you haven't run into it yourself.

It gets worse when you are talking about ancient scripts, because they
might not even have Unicode code points (that is, assuming you buy the
invalid assumption that something is displayable if it exists in the
Unicode code space).

I ran into this problem just a few months ago, after looking up dozens
of glyphs in the charts, not finding some glyphs, and then found that
I needed to change most of the others to images (with appropriate
alternate text, of course) after finding that they are not displayable
on most systems.

If you can split everything out to figures, of course it would not be
a practical issue because you can just float the images. But
somethings the glyphs must be kept inline and must display by default
at roughly the same size as the text.
