Airbus has automatic turn coordination, but if it happened for some reason to not work, I don't see any reason why not to use the rudder and do the job.
Sideslip should be demystified, I'm practically sure that Airbus and Boeing have very good models for simple movements around the yaw axis, why not do it in the sim ? Do a little dutch roll to see how it handles.
On the fun side, using the rudder in an A320 type will create an artificial wind on the ND. Try it and see for yourself
