I really like this space. I prototyped a concept last year for product/qa teams to write the tests, I was able to run Playwright in a docker container and stream the session to the browser using VNC and web sockets to extract the test recorder and relay commands, allowing the user to run Playwright and record tests without needing anything installed.
It was a lot of fun, but what turned me off it was the likelihood anyone not already using Playwright would have to update their frontend and keep streamlining that before they really got any value out of it.
