It would be great if eRPC had the option to completely block batched requests. Even if you use rate limiting on e.g. AWS WAF rules, a single user could sneak in a huge batch of 100+ requests in a single request, technically bypassing the ratelimit and making eRPC slow for others to use.

Enabling rate limiting on eRPC's side is also not enough, because if one is using e.g. a reverse proxy, all clients' requests will seemingly come from the same IP unless support for x-forwarded-ip is added.

Describe the solution you'd like
Just a top level config on erpc for something like allowBatchRequests that defaults to true. If set to false, any JSON-RPC requests with a JSON-array that has more than a single top-level item should be not allowed.
