I feel these ecmxist precisely because endless scrolling doesn’t. These load more, but I’m not sure the apps ever unload, so for the optiomization I understand why they have implemented this as they have BUT for me that way is just an excuse to be lazy with garbage cleaning. And these also might be one of the biggest reasons why the trending stuff doesn’t stick on Mastodon; Mastodon users don’t sort by popular, and while scrolling by chronological order, these things create obstacles for seeing all things posted.
