The public_suffix_list.dat included in the publicsuffix2 package is now quite out of date.
While one could use get_base_domain() with use_fresh_psl=True, this isn't done by checkdmarc's public interfaces, and would be a big performance hit to download the PSL on each call.
The publicsuffixlist package now includes a weekly updated psl.dat (https://github.com/ko-zu/psl/issues/25), and handles reserved domains sensibly out-of-the-box (#39).
