I have a notion that some of the "arranged" books of piano classics are intended to tailor the material better for small hands. Or even, young hands (middle-schoolers, etc).
In some instances, the versions in the "arrangements" are not particularly easy. But they never have stretches beyond octaves, if even those.
I don't know how youngsters could play some of the pieces with the 10th stretches, especially where they are very common. But there are some amazing kids out there.
Try Alexander Tcherepnin's "Bagatelles" sometime. Tenths are as common for him as are octaves in other composer's pieces. There are -- not seldom -- stretches beyond 10ths where I have to cheat one way or the other. (Roll, change the chord, whatever.)
I sympathize with the one poster, above, who can just make a 10th, but not when it involves a lower white to an upper black. I can just barely do that. But never an 11th.
