Thanks, I don't see any mention here that makes me think that Flang isn't the core tier, do you read anything differently here?

By "this issue", do you mean the "OOM on Windows" issue? 
If so I agree with you, and I agree that disabling flang as a dependency to fix this error is the right course of action. 
But I'm still puzzled as of why we'd not just do this for Windows where the issue exists and leave the Linux flow as-is, mind elaborating on this?
