I have spotted that the size of .orig.tar.gz is much larger than the size of
generated .deb files... primarily (besides missing -doc package ;) ) it is due
to some  data files used for testing not being installed (package_data in
setup.py), which leads to failure of unittests when ran on mne "as installed":

hi,

do you have any idea why this happens? these files are excluded from
the manifest to avoid
a huge upload to pypi but could be shipped on debian. Any idea how to fix this?

thanks
Alex

I tried integrating the additional external data into the test suite.
Even when downloading only the minimal test data, it amounts to over a gigabyte of data.
I consider both the effort involved and the resulting repository size to be excessive, especially given that many integration tests relying on data are already running, and this would add only 705 more.
current tests === 4775 passed, 1745 skipped, 2 deselected, 7 xfailed in 709.79s (0:11:49) ====
Of these, 705 were skipped due to "Requires testing dataset".
