"792 sponsors are funding Homebrew’s work." on github alone, and there are more on the Patreon and donating directly. Your name is not in the README, so you are on the bottom 4 tiers, they get at most $30/month from you. For $30 (or less) a month, I don't think it is reasonable to expect them to do extra work to support an a 4th OS version. This is less than half an hour of work at commercial company rates, probably much less. If they have limited resources, I'd rather them improve support for the modern OSs, instead of spending them on old stuff.
