Why are you and other defenders of the Anubis approach so fixated on this one specific limitation of a certain type of scraping architecture? It’s hardly an immutable characteristic.
You say “they” as if all scrapers are a monolithic group with the same constraints and goals. Part of the problem is the massive diversity.
Why do you think anyone thinks it's immutable? Do you understand the basic concept of an arms race, or cat and mouse game?
