Only partially. The primary issue this bug report is about is specific only to Piglin Brutes (from what I've found). The bug report you linked talks about the behavior of the amount of steps the mob will take (so the stuttering issue), but not the fact that Piglin Brutes are the only mob I found to strictly only detect players at a follow_range of 16 despite the player being able to edit the follow_range attribute. Other mobs seem to function fine.
