The first time I swapped the keyboard, I did break the screw hole on two of the screws (one black one and one silver one) near my tab key and the volume up/down keys over a year ago. I use them often and have had no noticeable difference. The amount of increased flex is low enough that I cannot notice it, and no components of the keyboard that carry electronics touch the underlying components even if you were missing many more screws from what I can tell.
Having done this now 3 times, because I can't decide on a layout, I absolutely agree this is NOT a 00:15:00 - 00:30:00, but at least 30 minutes. I clocked myself at 42 minutes on my most recent keyboard swap, and that is with prior experience. Screwing and unscrewing 75+ screws with precision is not a 20 minute job. You will be hunting for where the last one or two screws come out for at least a few minutes, and then again where the last few go. I can guarantee no first time Framework keyboard swapper is doing this in under 45 minutes.
I would say this procedure is not difficult, it just takes time.
