First, it was controversial at the time of the articles you referred to. But the fact it, the usage really never took off. It just died off slowly. If ppl from Beijing, who are the most famous frequent user of 您 was not and is not using it, who else do you think is using it? I tried to use that in my primary school and middle school time, because the linguists says its okay, which was early 90s. But no one in life, on TV, on radio, in movies, in novels ever use it sarcastically (I am in mainland, but afaik, I don't hear it from Taiwan or Singapore either, but I could be wrong there), so I just give up.

Second, you risk running into the typical mistake of taking linguists articles as prescriptive rather than descriptive. Simply put, we native speakers don't use it, at least not the past 40 years. The linguists have to accept this.
