OK, that seems like the sane way to handle anything like that, if you want to handle it at all. And there is absolutely no reason why Linux should do it differently. A userspace tool like the mtp tools could do the exact same by writing a new udev rule for the crashing device. There is no reason to hardcode these kind of really, really, really buggy device workarounds, making other devices suffer because you are afraid to request descriptors.
