What Impact Does Parachain Auction Have on the Polkadot Ecosystem?

1. Do all Polkadot ecosystem projects need to bid for slots twice? PolkaWorld: This depends on the situation of the ecosystem projects themselves. Currently among Polkadot ecosystem projects: If an ecosystem project only has one network, they can choose to only bid for Kusama parachain slots, like KILT; or only bid for Polkadot slots, or they can also bid for Kusama first and then switch to bidding for Polkadot, like Bifrost.
