p2p – An explanation of the decision to only allow flooding of outgoing connections on Erlay

I was reading BIP-330, outgoing connection Not enough fan-out.

The main idea is that many nodes want to receive transactions in the first cycle itself. private node Do not allow incoming connections. The only way to get a transaction is through: Reconciliation . Wouldn’t this lead to the problem that public nodes will almost always have more transactions in the sketch than private nodes, causing private nodes to always fall behind in the mempool?
