Regarding bug #34027, I brought up a suggestion on how to fix this. But it doesn't result in any improvements:

Do you guys think importing TPL DataFlow sources from corefx (not referencesource) is good or bad idea? So far I have no idea if the API is different or not.

TPL DataFlow has official nuget. I don’t think we need to build it (edited)

Oh interesting. But the problem is that we do ship that assembly and people hit some bugs. https://bugzilla.xamarin.com/show_bug.cgi?id=34027
No more arguments followed.
At this state, it seems that mono should remove System.Threading.Tasks.DataFlow and let people use the ones in the PCL.
I think it is not always good because if there is any open source projects that are distributed as part of some Linux systems (because PCL are distributed as binary) it is going to be problematic. But maybe that's not Mono's responsibility.
Anyways if we don't do anything, that's the worst.
