Yes, but not without making sure to spend the effort to educate that this is OPTIONAL to be set by an SPO for added flexibility of varying use cases and collaborate with wallets to clearly distinguish "open" and "contingent" pools from each other to try not to worsen the UX for delegators too much (it will get more complicated either way). Crypto media will quickly weaponize this as "Cardano becomes a permissioned blockchain" hurting our perception, if we don't have clear preemptive messaging.
