The linter (i.e. cpplint.py) no longer needs to check for alpha-sorted include directives because our source formatting (i.e. clang-format) will take care of this by now. This is the current default configuration of the underlying linter anyways. Note that the two tools disagree about the correct ordering about files containing dash characters. The ordering suggested by the formatter is more natural. Having the formatter trigger linter errors is not a good situation to be in.
