If you use VMix or OBS in conjunction with EW you can fake this with a little work. We use the VMix NDI Desktop capture app which is free and run it on the EW computer. It's been super reliable! It will make all screens and windows available to VMix or OBS via NDI. For EW, the foldback view provides the clean background on the lyrics and can be made transparent in VMix/OBS. The challenge for us is the CCLI info isn't included on the foldback, even as an option, and we need to include this in the livestream. So you can create a new template in EW that bumps the song background image up just a little so the CCLI info is in a solid color background at the bottom. Some may not like this aesthetically for in-house, so you need to decide for yourself. In VMix/OBS you can pull in both the foldback and the live view with image background into a single overlay for the livestream. Using the size and geometry controls in VMix/OBs you can crop and realign the two EW screens so they look as one with the background image cropped out. Once set up, it's easy to make the lyrics appear onscreen in the livestream. Other than the setup time, this new EW feature probably wouldn't change how we use VMix on the weekends nor would it change the EW operator duties. Maybe that helps someone.
