We're all sending JSON around all the time, it's not really that big a performance hit, especially in context of the formats transiting networks today (it's the same, lots and lots of JSON)

The firehose is CBOR, jetstream is JSON (which more people use)

I was mainly speaking more generally than atproto. Most APIs talk JSON these days
