Not always in larger sets. But like who would buy an SAE set of any size
if it ran from say 3/8 to 3/4 without a 9/16?

Depends what's missing, I suppose. I used to rarely find things that were
11mm. 8, 10 and 13mm were very common, and everything else somewhere
inbetween.

Personally I like having at least a couple of everything in a variety of
socket depths and drive sizes.
