For my use case it would be nice to have some keywords to be able to deal with elements that get removed from the DOM. Something along the lines of

• Wait Until Element Is Stale
• Get Element Staleness
• Element Should (Not) Be Stale

I wrote a rudimentary Python plugin at work using Selenium's staleness_of condition. I got the OK to use the plugin as a base and spend some time so I'd be willing to try and provide a PR as well if this feature makes sense and would be a good fit for the library.
