Use JSON stream (application/x-json-stream) serialization?

It looks like the Application Insights SDK for .NET uses a JSON stream serialization. See:

• https://github.com/microsoft/ApplicationInsights-dotnet/blob/ed0015a78a53b3a26e04d18eed442581bc7c571f/BASE/src/Microsoft.ApplicationInsights/Extensibility/Implementation/JsonSerializer.cs#L42
• https://github.com/microsoft/ApplicationInsights-dotnet/blob/ed0015a78a53b3a26e04d18eed442581bc7c571f/BASE/src/Microsoft.ApplicationInsights/Extensibility/Implementation/JsonSerializer.cs#L227

If I read that correctly, it's newline separated objects instead of an array.

[{"data":{"baseData":{},"baseType":"RequestData"},"iKey":"0fdcec70-0ce5-4085-89d9-9ae8ead9af66","name":"Microsoft.ApplicationInsights.Request"},{"data":{"baseData":{},"baseType":"RequestData"},"iKey":"0fdcec70-0ce5-4085-89d9-9ae8ead9af66","name":"Microsoft.ApplicationInsights.Request"}]

{"data":{"baseData":{},"baseType":"RequestData"},"iKey":"0fdcec70-0ce5-4085-89d9-9ae8ead9af66","name":"Microsoft.ApplicationInsights.Request"}
{"data":{"baseData":{},"baseType":"RequestData"},"iKey":"0fdcec70-0ce5-4085-89d9-9ae8ead9af66","name":"Microsoft.ApplicationInsights.Request"}

I imagine the benefit is, that it can in theory start sending and receiving telemetry data while more items are still being serialized. Would it be useful to do the same in this crate?

It looks like the Azure Monitor OpenTelemetry Exporter for .NET uses newline separated JSON objects, too:
