Always good to know your stuff, but no need to evaluate yes or no: It’s definitely a yes. It will be enabled for new folders by default in what’s probably to be v1.1.0 (or v1.0.2 if not). The only reason it isn’t enabled everywhere by default is, that all connected folders should have it enabled (there shouldn’t be a mix).
Only 400GB here, but 5% of roughly 40k reporting users have >600GB data, so 2.5TB isn’t that special. You just have to keep in mind it needs to hash all your data, and then compare those hashes with all connected devices on first sync - that will take some patience on your side if you keep monitoring it
Also don’t try with 1.0.0 please, wait for 1.0.1 (released tomorrow) - it’s worth it
