Hi, I found this gradle property in kotlinx.coroutines repo: kotlin.mpp.enableCompatibilityMetadataVariant=true

What does it do exactly?
I'm interested because I'm in the process of testing publishing and consumption of multiplatform libraries (Android, native, JS and JVM).

If I understand correctly (from kotlin code and some info in the internet) it needed if you are enabling HMPP (enableGranularSourceSetsMetadata=true) and want to allow users which don't use HMPP to consume your library

@elizarov Can you confirm? Anything to add?

Also, is it related to that issue? e: Could not find "kotlinx-coroutines-core_concurrentMain" https://kotlinlang.slack.com/archives/C1CFAFJSK/p1597886480055300

[elizarov]

Yes. It makes it compatible with non-HMPP consumers, generating old-style metadata, too.

what is HMPP?

Any reason this is not the default? It feels like this is what most people want?
