As a workaround I have been using https://github.com/awaitility/awaitility

This was opened 8 months ago. Curious if there's been enough interest to actually implement or it's just fallen off the roadmap entirely? Personally, there are use cases where I prefer toBeVisible() with pass / failure, and other times I actually just want the boolean from isVisible(). Having the ability to poll on a method like isVisible() greatly extends the usability for async functions when I'm testing the positive and negative outcomes in subsequent tests.
