Even if it weren’t, at least some amount of thinking should be involved in requesting it, and e.g. don’t do it on feature requests or API defect problems. But they do, oh they do.
It should also be noted that it doesn’t save time: it off-loads some time wastage to an external developer who is filling the bug. And who has to pointlessly collect it (it takes several minutes and knocks your system off), then upload 200-400MB file to a notoriously crappy form that it will time out or error out, or sometimes say the upload was successful only to get a bitchy QA reply a week later to upload sysdiagnose.
A few years back, I had a sysdiagnose so huge that Radar just wouldn’t take it. I spent an hour trying to upload the damn thing and eventually uploaded it elsewhere and posted an URL.
To this day, that sysdiagnose file was not downloaded a single time.
