I don't have a problem with stuck sparges. None. There's no argument here. This process is put forward as somehow "necessary". Newer brewers will read that and accept it. They'll then repeat it as if it were gospel. Nonsense. It's simply NOT NECESSARY. Do it if it makes you feel better, or if it looks better in a jar, or for whatever reason you choose to do it. But I don't prefer to add unnecessary steps. With all due respect, YMMV, you're free to do as you like, et cetera.... have it your way.
Pistols, here's the conclusion from your source (emphasis mine): "I think that this is an advanced technique for the home brewer and that you should not worry about it as a beginner and even a veteran should only try it when there is interest in this subject. I like to do it because it makes me feel good about my process and it does offer some advantages. Once I figured out how the malt should feel, there were no more messes with the mill either. The mash seems better suspended, which should be a good thing especially with thin mashes, but the lauter can still get stuck when using lots of grain. But that must have to do with the amount of flour that is produced with my tight crush."
Your source and I seem to agree about this technique.
