I asked Demur to keep HAS_ARG(). Not really for backward compatibility, but
for the dis module: to keep a nice assembler. There are also debug traces
in ceval.c which use it.
For ceval.c, we might use HAS_ARG() to micro-optimize oparg=0 (hardcode 0
rather than reading the bytecode) for operators with no argument. Or maybe
it's completly useless :-)
