It gives the pilot an excuse to completely avoid learning how to land the A/C manually,
Really do have to laugh at people who refer to this as flying and the skill of manual landing. Its a computer controlled RC drone. You don't "fly" it, you simply move it.
You need no knowledge of aviation, physics or anything of the sort. It requires no aviation related piloting skills what-so-ever.
"Manual landing" a mavic consists of moving a joystick downwards. Nothing else. Its hardly trying to fly a full instrument approach single handedly in foul weather!
It's so easy that (quite literally) even a child can do it.
I struggle to see the issue with the massive "skill" of moving a joystick down vs pressing a "come home" button.
Precision can be very useful for making sure in the event of an RC failure, a lock up rendering the drone uncontrollable and so on actually lands somewhere safe in an area where it isn't. Even fields and car parks can have rocks, dips, weeds big enough to foul the props so you really do want it accurately landing somewhere without those obstructions if you are no longer able to control it.
If im not on a boat i'll do a precision take-off 100% of the time to ensure if the above happens, worse case scenario is it gets itself back safely. 90%+ of the time i'll hand catch to avoid dust and debris into the drone but if i do decide to hit RTH i dont somehow feel like ive "lost" that massively honed skillset to work a down joystick.
I'm wondering if the mavic will now do precision takeoff by default hence the lack of an option - maybe someone can actually test this? Do the usual, take off, climb to 30ft, fly around, hit RTH and see how accurate the landing is. The compare with takeoff, fly to 2m or so then move it and try.
