It seems that if "visibility:collapse" is targeting the same kind of dynamic scenarios as in tables, it should behave exactly as "display:none" in flexbox (no extra spacing in justify). It doesn't seem super useful then - but it does make it easier to show/hide items without wiping their 'display' property (your favorite inner/outer display issue).
