Yeah, I agree being confused about how your phone works is pretty funny.
Also, while we're at it, the reason the 6+ doesn't have 8 rows in Standard view is the same reason it doesn't have 5 columns. Each icon and label is about 100 pts (compared to 90 pts on the 6), and with only about 700 points to work with after the status bar and page count, even if they had used the tighter iPhone 6 padding, going to 8 rows would run out of space (90*8=720).
So again, if split views, landscape home screen, and multi-page landscape folder views (and whatever Plus-only layouts developers come up with in the coming months) aren't important, and you want to undo the larger text of Zoom by manual override, then by all means use Zoom to get those bigger icons on the 6+. But it's a pretty bad trade for just about everyone else.
