It is nice having a cutoff point, so I haven't seen a push to raise it. Partly because we are doing a better job of defining/performing the risk part of the analysis.
I see less of the demand to wear full PPE when simply walking into a room. I would like to think it is because more safety experts are understanding the nuances of NFPA70E, like equipment doors and deadfronts are not always synonymous, but I doubt it is.
I had a client here in Arizona that went the other way. They lowered their go/no from 40 cal/cm^2 down to 12 cal/cm^2. The reasoning is if it is greater than their daily wear, they won't work on it. Instead they hire a contractor or call the utility since this only affects their main incoming switchboard.
Your point about "doing a better job" couldn't be more spot on. Thanks to years of people (many here at the forum) helping people better understand the hazard, risk assessments, PPE, studies etc. It has been on monumental group effort and thanks to all those involved!
The motto for the IEEE Electrical Safety Workshop held every year is "Changing the Electrical Safety Culture" It has been steady progress and we can safely say the culture has changed for the better - with the help of more people than we can count. Keep moving it forward!
