I don't speak for the compiler devs, but IMO, one-letter variables are
OK if they are local, and cover a relatively small scope.  Java-style
verbosity IMO makes code *harder* to read because the verbosity gets in
your face, crowding out the more interesting (and important) larger
picture of code structure.

As Walter said in his recent talk, the length of variable names (or
identifiers in general, really) should roughly correspond to their
scope: local variable names ought to be concise, but global variables
ought to be verbose (both to avoid identifier collision when a larger
amount of code is concerned, and also to serve as a convenient visual
indication that yes it's a global).
