I think we would probably not want to make this a part of our official SDK API surface area. It's an internal utility class, and that's not really the business of the OpenTelemetry SDK to be publishing.

maybe not in this form, but I could see an argument for declarative config supporting this in some way that doesn't require copy-pasting this code everywhere (https://github.com/open-telemetry/opentelemetry-configuration/blob/main/CONTRIBUTING.md#properties-which-pattern-matching)
