Discussed several times.

The stopping requirement for landing (LDR), with at least the same amount of flaps used for take-off, is always less than the ASDR requirement. For the latter the most critical case being V1-stop with all engines operating.

Distance is not an issue unless non-normals come to play or the pavement friction degrades significantly.
Structurally, the weight is never an issue.

The trouble lies with the approach climb gradient. The lowest certified landing flap may be more than the one used to depart and the 2.1 (certification) 2.5 (PANS OPS) might not be there. Hence the performance OEI for GA becoms an issue for the longhaul types with a large difference between MTOM and MLM. In other words, if the T7 can do it, the 320x certainly will too.
