It definitely manifests in ways I can see. I struggled for years as an end user of selenium with backwards compatibility issues, bugs and weird browser quirks.

It's pretty apparent that it requires an awful lot of maintenance to keep up with the browsers, so if this really does reduce the workload on them then that ought be noticeable on my end with fewer bugs, quirks and backwards compatibility issues. This is more exciting to me than all of the other features (I'm a bit dubious of the ability to detect if a page has really 'loaded', for instance).

In my experience, playwright is a lot, lot better on this than selenium.

You can even choose different events to wait for!

That said, there's no accounting for developers who think FOUCs are normal, etc and generally make your life as a tester and end user difficult.
