I hate the consensus view every time this topic comes up. It is way more humiliating and disrespectful to give someone a point. You are compounding two problems by doing so: you are making it even more clear that your opponent is unable to earn a single point on their own merit and second, that the point they do have was not earned but donated.
When I play someone whose level is astronomically higher than mine, I want to get destroyed. I want them to play at their full effort and experience their level of play and try my best to earn each single point by trying out different tactics or trying to identify opportunities. Those are some of my most treasured experiences in playing and surprisingly hard to come by. If 11-0 is a true reflection of the game when both people are truly playing, then what shame is there in that? I don't see any at all.
When I play someone whose level is way below mine, I place constraints on myself, but still always play full effort. A common example is lower level players often have difficulty dealing with serve variation so I will get rid of that and pick one serve to use every time, commonly long backspin to backhand side. Or maybe I will think to myself, try to extend rally to at least 2 shots before allowing myself a loop or otherwise offensive stroke. Using these constraints and varying the amount of them I can make sure I adjust my level of play as to prevent the score from ever reaching 11-0 but at the same time never lowering my level of effort. This seems contradictory to the way I wanted to be treated in the reverse situation but in a non-tournament setting I have found this to be a good way to maintain the respect level. In a tournament though I don't hold back at all, for the same reason I stated previously.
You can beat someone 11-0 respectfully. It is all about how you carry yourself. I find that the "too nice" people are more annoying than the people who recognize the reality, carry out the game, and finish the game in a straightforward manner.
Fearing the 11-0 on either side is immature. For the winners consider that the losers don't want your pity. For the losers, it should fuel the motivation from savoring the experience of a level of play that is hard to come by in normal playing.
