Yes, they should. However, just because people shouldn't be doing something
doesn't mean you should ignore the fact that they are.

Responding to a deficiency in an area which Tor does not attempt to solve is a poor use of resources. Tor is a strong-anonymizing proxy. Three hops is the minimum necessary to ensure a proper degree of anonymity. There are severe deficiencies with only using one or two hops insofar as anonymity is concerned. Using more than 3 is problematic from a network utilization standpoint. Thus the magic number, three.
"There are many use cases where that level of protection isn't required." -- In that case, use a tool better suited to your goals.
Now, if you were interested in coding this piece, and you felt it a good use of your resources, then it might be worthwhile. However, remember that every choice given to the end user is a chance for the end user to make a bad or misinformed decision. Tor has bandwidth issues that come with multiple routing hops. Many users "just want Tor faster", but often are not savvy enough to understand that reducing the number of hops, even by one, severely limits the Tor's ability to hamper tracking efforts. As such many may choose to reduce their hops, and get faster usage, but falsely believe that just because it is still "Tor", they can't be tracked.
