the proposal looks very interesting! especially the aggregation part! (would be even nicer if u could share some metrics here)
Indeed I have some concerns, while providing token issuers with the ability to choose which bridges to support can offer advantages in terms of control and risk management, it can also potentially lead to the concentration of funds in a limited set of solutions. Token issuers may have biases or motivations that go beyond technical metrics when selecting bridges, which could influence users’ decision-making. This could reduce diversity and limit the number of available options for users.
The EIP proposal, with its fragmentation and aggregation solution, may indeed make using the bridge supported by the token a more economically attractive option due to potential savings. This can create an economic incentive for users to prefer the bridge selected by the token issuer, even if alternative bridges exist. Users may prioritize cost savings and convenience, which could result in a concentration of liquidity and usage in the chosen bridge.
