Unless you operate in extremely short runways, Using the EFB, an A320 max landing weight at 64.5T in ISA condition and no wind will have a landing distance of only 2350M with auto brake medium with No Flaps and No Slats with a VAPP of 185kt and only 1750M with manual braking. You would have to land way past the TDZ in normal condition to overrun this aircraft.
Not saying that it can’t happen, but that’s not the biggest concern. In worst case I rather overrun the end of the runway at 20/30 kts than crashing short of the threshold.
Edit: I’m not adding « couple of knots »on some aircraft because I’m scared to stall but to have better control while flaring and to lower the pitch on old A319 with conf 3.
