Also, as someone on the periphery of Selenium (mostly via WebDriver), some of the challenge is that Selenium has a huge amount of test code already written for it — and making radical API changes would break every test already written for it, and at that point you’re effectively a new library.

It’s gonna be very interesting to watch exactly how the adoption of WebDriver BiDi goes with Selenium, especially once WebDriver Classic starts to go away, and how API stability is balanced with exposing more and more async capabilities.
