Is it allowed to add other formats to performance testing?

I'd like to write benchmark for System.Formats.Cbor, but this library does not support encoding/decoding with stream and high level serialization from object to data and data to object, but it may by usefull for testing CBOR performance testing. But I wrote a high-level library for my project, and I think it could be useful and used in the same conditions as the implementations presented in the benchmark. Is it allowed to add benchmark in [that](https://github.com/dotnet/performance/tree/main/src/benchmarks/micro/Serializers) place or System.Formats.Cbor is not that type of libraries and is should be placed in another directory?
