At some point they lost that focus and dropped the ball. For example for a very long time they had no direct support for reactjs even when it was hugely popular, instead you had to go find some third party library which is a terrible thing to have to do for implementation of payment code.

Maybe they’re improved and started supporting actively the technologies developers are using.

Looks like they were partly generated, otherwise it would be impossible to keep everything consistent - especially with the many language examples. They also seem to generate an OpenApi Spec (or use this as a basis for generating the docs?): https://github.com/stripe/openapi

There have been. The following is a good search to use to find other discussions.
