What is the point of rate limiting the gRPC API? I mean the CallRateMeteringInterceptor class etc. From what I understand that API is meant to be used privately/locally, but when integrating it I found the rate limiting to be an obstacle actually and I had to use artificial delay to avoid being rate limited. At the same time it seems to be non-negligible amount of code in the Bisq app to implement these limits.

I would assume that anyone who writes integration code can be responsible enough to not overwhelm/kill his own node with too many requests.

Happy to hear what was the rationale which justified introducing it.
