What should the default MetricReaderType be?

[alanwest]

Can we settle on a universal default for MetricReaderType (manual vs. periodic), or should the default vary based on the type of exporter used (OTLP, Console, etc)? This question was raised here.

#2717 moved the notion of MetricReaderType to the SDK for configuring whether to use the periodic metric reader or the "manual" one.

Currently, we do not have a universal default. For instance, when using the helper extension methods AddConsoleExporter and AddOtlpExporter the defaults are MetricReaderType.Manual and MetricReaderType.Periodic, respectively.

A prior conversation posed the question of whether the Console exporter should default to MetricReaderType.Periodic.

ConsoleExporter spec (https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/sdk_exporters/stdout.md) says it is a push metric exporter, which says it receives metrics from a paired periodic exporting reader, which says metrics are passed based on a user-configurable time interval, with default as 60,000msec... Same for OTLP too.

Unless I mis understood the spec intent..

Closing, as there is no MetricReaderType anymore.
The defaults are covered by spec and being implemented in the SDK/Exporters.
