Once either indices, datastreams or their aliases become very numerous, these checks of adding everything to a fresh set and then retaining collisions become very expensive. Slightly adjusted the logic to just collect collisions instead to save endless set adding. Also refactored the logic a little to make it easier to profile the time spent on these validations and extraced some cold-paths for maybe a minor speedup.
