IPFS Gateway 汽车文件请求的 carV1 与 carV2 的现状

Question

在通过 IPFS 网关为下游实现请求汽车文件时，我想了解 CARv1 与 CARv2 的当前状态. IPFS 网关实现是否会持续返回 v1 编码的汽车文件，还是有可能改用 v2？如果能对CARv2在IPFS网关实施中的流行情况和支持情况有任何见解，我们将不胜感激.

To specify the explicit version in the content type header, you can use the following format: Content-Type: application/vnd.ipld.car;version=1. This specification will be recognized by valid gateway implementations, as outlined in the documentation provided by IPFS: Trustless Gateway Specifications. It is worth noting that utilizing version 2 on a trustless gateway may not be the most practical approach, as there is currently no cost-effective method to verify that the index has not been altered. Regarding the format compatibility, it is possible to read a carv1 stream and simultaneously generate the v2 index incrementally. However, it is uncertain whether this functionality has been implemented in the car libraries.
