csbindgen is designed to return primitives that do not cause marshalling. It is better to convert from pointers to Span yourself than to do the conversion implicitly and in a black box. This is a recent trend, such as the addition of [DisableRuntimeMarshalling](https://learn.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.disableruntimemarshallingattribute) from .NET 7.
