Yeah, i agree, i was not supporting being pinned, neither do i find 1RM maxouts useful. It's not a coincidence that i've never maxed out singles or got pinned so far either. But it's understantable to try a 1RM sometimes. Maybe ego, maybe curiosity to see your estimated/real 1RM deviation, maybe to see how a block worked for you, whatever the reasons i am fine with them. But i am talking about spare testing, after a traning block or sth. To have them as a regular training element? As i said already, plain stupid in many aspects ( health aspect included first ).
More rep maxes e.g. 5RM are much more safe and ive done then a lot. You get the signs there, first reps are always easy and then each rep tells you what will happen on the next. If you grind and break your form at the 3d , heloooooo, just dont try the 4th.
