before I say more, I just want to clarify I meant no ill direction or intent your way. I genuinely think there is a fine balance to be struck between a good stdlib & just moving things into the broader module ecosystem for any language. Some get it more right than others (Go Lang, for instance, I think is cool, in that it has the stdlib, but if I understand it correctly the stdlib is maintained as separate installable libs)

Microsoft hasn't move much out of the core C#/.NET libaries, rather they made it easier to interop the SDKs/runtimes. The actual libaries themselves haven't changed much in respect to this issue.

The reason I don't believe it's a balance is simply that I haven't seen a downside. The world has drifted towards microlibraries largely because of real advantages, brought on by automated package management making them practical. People here seem to be grasping at straws to find a justification for disliking that change.
