I think, generally speaking there are a lot of contexts here clashing of what people mean by "feature" and "product". For some, "the product" might be a 30+ year legacy multi million loc codebase getting slowly improved, but still old and inadequate and probably full of technical debt and a lot of domain knowledge needed to navigate.

For others "the product" will be a website with a few 10k loc behind the scenes.

Getting a feature out in those two environments is not the same thing.
