can you use rel=opener with window.open()?

I know you can use "noopener" with window.open, which explicitly tells your browser to forbid the child window from accessing the parent window. This should have the affect of using rel="noopener" in a hyperlink.

However, Chrome 88 is soon (2021?) going to make "noopener" the default.

So is there a way to do the opposite, and explicitly set it to "opener"? So that the child window DOES have access to the parent window? I'm hoping to fix my link before it breaks with the newest Chrome.

I assume it'd be the code below? I'm not sure how I'd test this before the next version of Chrome releases. But I also don't want to wait to make this change until after my link breaks with the next release.

window.open(url,'_blank','toolbar=1,menubar=1,location=1,status=1,scrollbars=1,opener')    

or

window.open(url,'_blank','toolbar=1,menubar=1,location=1,status=1,scrollbars=1', 'opener')
