Not sure I can ever remember these so called long gimmes that you refer to.
I don't play coin rooms any more, even stopped playing the showdowns (firstly because of the forfeit glitch, and secondly because it is tediously slow), but I've either seen it once some time back or I've read it somewhere - hacks gimmes are somewhere around 6ft, which is quite ridiculous really.
I have never been a fan of automatic gimmes, neither am I a fan of 'agreed' gimmes at the start of a match; it is up to a player if he/she wants to give the other player a putt, even if it is just a foot away. Sometimes I will give a putt of 4-5ft if it is somewhere like St Andrews on hole #1 with front pin, but I wouldn't give a 2ft putt if it was above the hole on either of the two pins on hole #2.
Totally agree with you too Simon - one small step for man, one (or more) huge mistake(s) for WGT!
