Disabling the proximity detection is not a good idea in general, because if you forget to turn the screen off before placing the device back in your pocket then the display may remain active for an undetermined period of time.
That said, disabling the proximity detection in landscape mode can be a good choice to avoid the screen going off while reading in landscape mode. At the same time it is not so dangerous unless you put the device back in your pocket (or handbag) horizontally forgetting to turn the display off, the combination of the two being hopefully unlikely!
