My fear is dutifully curating lists for this purpose -- which would take ages -- only for them to monkey with this feature. I see a lot of people on Twitter who say something like "if you put me in a list, I will block you," which makes me think there's some sort of list-spamming capability currently. (I can't figure out any other reason people wouldn't want to be added to lists...?)

I use the reverse-chron feed almost exclusively. Product Management Twitter has devolved into people with 1-2 years of product experience vomiting out threads of "What I've learned" that have zero insight, and because I follow a lot of legit product people, Twitter thinks I want this other stuff. I hate it.
