Hence there are zero internal imports, and the whole datasets submodule can
then very simply be stripped for space-constrained usage scenarios. (in
those cases a separate package would help even)

I believe that one of the motivations for adding the ECG dataset was to
make some of the scipy.signal unit tests more realistic. Is that something
you'd like to forbid? On the one hand, if you're strapped for space, you
probably want to remove the test suites as well. On the other hand, you do
want to be able to test your stripped installation!
