I just went and read the blog post again (here if you haven't seen it): https://godotengine.org/article/gdscript-progress-report-new-gdscript-now-merged
Now I think I would say I agree that the changes to seem to make the language a bit more confusing. GDScript was very easy to learn and use, so I can see how making it more complex can be an issue. That said, the new syntax is a welcome addition in many cases.
So I think it is an improvement, and if it helps performance, and code completion, and type safety, etc. then I think the change is for the better. And new users don't need to use all the features right away, so I don't think it will be a huge concern.
