Blip curious observation, but we can use all other instrument approaches available (and more importantly their corresponding alternate minima) ILS, LLZ/DME, RNAV, VOR, NDB. The point that had been made earlier (and my experience backs it up) is that we often get dodgy cloud base, precipitation and visibility information from the ATIS/Tower at certain "Regional" ports. Most of us have whizzed in on a DME arrival with the expectation of becoming visual and discover the said conditions are certainly not present. I think the point being made earlier is that if there is any doubt we simply plan an alternative instrument approach. Easy and safe. Why make life difficult flogging about and "wishing" each other to call visual?
Centaurus out of interest what aircraft type do you fly, and what rank?
