I think we should add wikihow family farm to pywikibot/families. Wikihow is actively used, it uses mw 1.33 (unfortunately 1.33.0-alpha) and there are some bot owners using pywikibot for these sites.
The main reason to include it to our families is that wikihow has ist own behaviour replaceing normalizing page titles: Here a hyphen is replaced by a white space character. There own Family may handle this but one created by generate_family_files Fails here.
See https://gerrit.wikimedia.org/r/#/c/pywikibot/core/+/547015/ for this case.
