My company has an internal limitation on visibility and cloud base for a raw data ILS (AP and FDs off). Hence, it's perfectly fine to practise in non-demanding conditions (and it's actually a good idea to be prepared for the day when the magical bars might fail). In marginal weather, however, it's safety first, just as anytime in aviation. And if that means lowering your workload by using more automation - so be it. As a pilot, you are there to find a safe solution to whatever is thrown your way.
