Yes, it will be.  I still maintain that snapping handles to grid positions is limiting as far as control of curves goes, but people insist it is important, so I'm adding it.   You will be able to snap handles to anything that you can snap nodes to. But, the option will have to be turned on as an additional snapping option for the Node tool.  This will work in addition to all the smart snaps I've added for setting handles directions and lengths.   I'll do another video soon to show this...
