HF there is another matter, which is the published performance figures.

These assume a correctly-flown approach - i.e. on glideslope and hit in the TDZ. If you do that, and the figures say you can stop in the distance available, then you can (and the editor's decision is final ).

If you come in at a shallower angle, but with the same speed, then it is because you have more engine power on than for a correctly-configured approach. With a lower rate of descent, same speed and more engine power you actually have a higher-energy approach. As you come into ground effect that will give you a bit more oomph than you really need. Big engines take longer to spool down. You don't want that!
