FYI this will work fine today for metrics & traces because they have different options classes. Logging appears to be sharing GenevaExporterOptions with tracing so if/when logging gets hooked up to DI/options there will be issues with the delegates potentially clobbering each other. Cross that bridge when we come to it 😄
