I think any improvement to accuracy is worth it. I could see bickering over the word "substantial". Perhaps "reasonable evidence that it improves historical accuracy" would be a better and more challenging criteria to meet?

Btw. I know many people like the installers and that they both take effort to set up and work reasonably well. At the same time I am fairly suspicious of them. My setting keep being reset and I had hand groomed the filelist.txt and organised it with headings before the machine "groomer" took over and undid my work...
