SL 5x5 recommends a perfectly sane method to deal with stalling - deload, work back up to the stall weight, and repeat until deloading no longer breaks the plateau, and then move to a 5x3 rep scheme like Starting Strength, and then (after another plateau) to 3x3.

Starting with greater volume gives the beginner more time to work on form.

Furthermore, if a lifter already has some training, it can absolutely make sense to increase the weight from the recommended start with the empty bar. Do 5x5, and if you have any left in the tank, add reps to the last set. If you get a set of 10, then increase the weight by 10 lbs on the next workout instead of 5. If you try to estimate an effective working weight, you're apt to overestimate, and end up plateauing too early.
