I agree with [MENTION=179963]cpach[/MENTION] bashing you a little on those comments. Of course I've made similarly biased comments too, some called by others and some not.
My only beef is with this........

I re-used the pin in my Shimano 11 speed chain after breaking it off and deciding I wanted to take another link out. Late Saturday night, everyone closed for the weekend. And I want to ride Sunday morning. So I re-used that tiny little pin. Had a dickens of a time aligning it while the chain was on the bike, but I did. And I felt the same reassuring click when I pushed it to the proper position that I've felt with every bike chain I've ever taken a link out of and reused the same pin from the 1970's to now.
500 plus miles so far on that chain, no issues. The link is marked. I have looked at it.
Recommended........... no, the pin is so small that alignment while pushing it in is difficult and will likely distort pin or plate if done wrong. But I don't think the peening thing holds true. All pins I've dealt with seemed to have a certain amount of peening. It probably does break off a feather edge on the pin or plate. But I bet enough is left to still do it's job when re-used. If you can get it aligned properly...... which was very difficult.
So while I agree, not recommended.. I don't agree with your reasons. I have not looked to see whether Shimano officially states a reason.
