Hi Thomas,
Yes. That is probably right.

It would be possible but a full implementation probably wouldn't be worth it.
We could add a workaround like the following to conf.py that would just render
the figure/table ref numbers as the target name as a fallback. That would allow
people to generate the docs with older versions of sphinx:
$ git diff doc/guides/conf.py
diff --git a/doc/guides/conf.py b/doc/guides/conf.py
index 1bc031f..bbf40f1 100644
--- a/doc/guides/conf.py
+++ b/doc/guides/conf.py

That is just a workaround though, and maybe not worth it either.
P.S. Also note, Sphinx 1.3.1 has a nice but very different default Html style.
