Describe the bug

hi
in my project i've configured msgpack as the format for APIs to use and all my endpoints use these formatters for all interactions
but identity endpoints still use json

using https://github.com/AArnott/Nerdbank.MessagePack with this config

builder
    .Services.AddControllersWithViews()
    .AddMvcOptions(option =>
    {
        option.OutputFormatters.Clear();
        option.OutputFormatters.Add(
            new MessagePackOutputFormatter(Witness.GeneratedTypeShapeProvider)
        );
        option.InputFormatters.Clear();
        option.InputFormatters.Add(
            new MessagePackInputFormatter(Witness.GeneratedTypeShapeProvider)
        );
    });

i would expect all input and outputs to be msgpack

Expected Behavior

i expect all the edpoints to use the same format
