they just need an explicit resync by sync1.1 today. but i actually think they should just be disallowed and we should enforce 1MiB everywhere (cbor, not sure if anyone has calculated the worst-case expansion size for json). arbitrarily-big: sketchy. app-specific limits: complicate sync1.1 handling

and arbitrarily-big probably works against the choice to use CAR serialization. i need to survey more libraries, but iroh-car can't handle blocks larger than 4MiB *at all*, it's hard-coded. (the CAR spec has no limits documented anywhere 🙃)

that language in the text isn't clear. big records should be disallowed. the '#sync' trick is for large batches of record ops
