Doesn't debugfs still cause crashes if there are ever files that can disappear from it, because it doesn't have proper lifetime management? Or did that get fixed eventually and I just missed it?

The case I'm thinking of is basically

fd = open(debugfs/file)
<wait, while doing something that causes that file to disappear, like unplugging HW>
read(fd) / write(fd) [depending on your access]
