is F4 full screen coming back?

Title says it all, just wondering if the F4 option will return at some point or if it has gone for good? If so, we need some other full screen short-cut for panel.
Thanks

Fullscreen Viewers
Floating viewers are not affected by the buttons in the Layout toolbar. You adjust the size of a oating viewer by dragging any corner of the Viewer window, or by double clicking on the Viewer’s titlebar. Additionally, a oating viewer can be scaled to fullscreen by right clicking in the Viewer and choosing Global Options > Full Screen from the contextual menu.
You can maximize one of the xed viewers to full screen by placing the cursor over the Viewer and pressing the F4 key. To restore a full screen viewer to its original layout position, press F4 again. This shortcut can also be used to maximize the Work area below the Viewers.

Tip: The Full screen option is only available in Fusion Studio

That's a different feature, and even if it wasn't, it's still not working in Fusion Studio either.

OK, I'll stand corrected.
