We don't.  But the complexity is often linked to the presence of
practical problems (e.g. lack of a good Free implementation, or lack of
a good multi-OS implementation, security bugs, performance cost, ...).

Other than the problems already mentioned with our SVG support, there's
also the fact that we don't have any way currently to auto-scale an
image according to the current face nor do we support using different
sizes for the same image displayed simultaneously in different frames.

So for "little images" in the modelines or in "list buffers" (like
dired), using special characters instead of actual images makes a lot of
sense (I suspect that it can be also significantly more efficient both
in memory and CPU use, but I don't actually know it to be the case).
