I see both sides of the coin here. My Note Edge, I have never had to do a battery pull to recover from it. Hell, the only reason I EVER removed the cover was to replace the stock one with the Qi wireless charging back cover.
I know in the days of old, this was a HUGE thing, but nowadays, even on devices that have no removable battery, there is a hardware key combo that does essentially the same thing. Never seen it fail unless it was a total hardware failure which would not have been helped by removing the battery anyway.
After taking to many folks, the vast majority don't really care one way or the other. It's just the few edge cases that get riled up. They brought it back with the S7.
My only real feeling about non-removable batteries, if you are going to keep us from getting bigger ones or spares, make the damn internal battery big enough to handle some serious usage, not just what you think it is the baseline, because that is always too low.
