lol, I hear you (and Patchou too I suppose), I had exactly the same frustration when Plus! hit me in the face with this "all your scripts are now disabled".
I too was literally like "WT##**BLOODY@@#CRAP**FU*KINGPLUS!" at that moment as I (and I suppose many others) are in the exact same situation: a shitload of scripts accumulated of the many years of testing, many of them enabled and many disabled and then going thru the list again and trying to remember what was enabled and what not.... Then I found that registry key and all was well (after comlaining to Patchou of course).
I wouldn't go as far as comparing it to some stuff what Apples does though. At least with this you _do_ have the choice and you _can_ change the behaviour (although it usually comes after the 'harm' done).
