Mostly it's about Go 1.22+ syntax with ranging over integers, but it also prefers ranging over slices where possible (it makes code a little better to read). Notice that we have a number of dangerous loops where slices are mutated during loop execution, many of these can't be converted since we need proper length evalutation at every iteration.
