[no_circuit]

If your binary has a small function set, probably not. But in a use case if you want to proxy/intercept cloud APIs, then something like Google APIs has 34K message types:

    git clone https://github.com/googleapis/googleapis.git
    cd googleapis
    find . -name '*.proto' -and -not -name '*test*' -and -not -name '*example*' -exec grep '^message' {} \; | wc -l

I think this more speaks to the tradeoff of not having an IDL where the deserializer either knows what type to expect if it was built with the IDL file version that defined it, e.g., this recent issue:

https://github.com/apache/fory/issues/2818

But now I do see that the 4096 is just arbitrary:

    If schema consistent mode is enabled globally when creating fory, type meta will be written as a fory unsigned varint of type_id. Schema evolution related meta will be ignored.
