Mode P vs Mode F

[AIRNUTS]

Is there a reason to have both modes F and P ?? why not to flight on mode F (functions) all the time since you have the same capabilities as mode P with the added functions ?? Is it safe to leave remote control on mode F all the time ??

When I fly in F mode I use the P mode as an emergency stop. It's came in handy when I set my litchi mission altitude to low and was backing straight into a tree.

I fly in F as I'm less likely to accidentally flip the switch up rather than down. I like Home Lock when I'm on my way back.
