Indeed.  The tarball above has ‘tests/requirements.txt’:

--8<---------------cut here---------------start------------->8---
pytest
pytest-cov
MarkupPy
odfpy
openpyxl>=2.6.0
pandas
pyyaml
tabulate
xlrd
xlwt
--8<---------------cut here---------------end--------------->8---

There are no optional dependencies in that file, though.  Or were you
looking at something else?

Let’s nurture it in Guix and move it to Guile when it looks better.
Likewise, we should have support for comments directly in (ice-9 read).
