It may seem "smooth" but I've been developing some hobby apps from time to time and it was never smooth. From Angular 2.0 release to 8 I've always had to spend 1-2 days to fix some random bugs from undocumented contract changes every time I came back to my projects. I'm speaking just from my amateur experience with 50 file projects.
