I’m willing to bet that the features you’ve seen removed are taken out because their utilization is low, and there’s some associated maintenance cost. I’d also like to know what other features were removed. I had never heard of subscription collections, for example, and a search returned [this video](https://youtu.be/qGSHPhR8k8g) (I wish markdown worked on here) that says collections were a test feature (I’m guessing it didn’t do well enough to make it to prod).
