In this case they didn't just plan, build, and release a feature in VS. They got all the way through the building and most of the QA for a feature in the core .net cli and decided to remove it, not for quality reasons, but because they wanted VS to have a feature others didn't. The work had been done and then they rushed through a PR to avoid community comment to remove the code. If python removed a feature so a specific IDE could have it exclusively I think people would also be upset.
