I agree with this completely and also think that it would be bad for the software to start passing rubbish (or garbage if in US) to syscalls expecting kernel to handle it in all cases. The only reason I point it out is because I expected some clever hacker to fix it *without* any obvious extra overhead, i.e. not by plain checking all the pointers etc. I certainly wouldn't want to see Linux benchmark figures to deteriorate only because it is generous enough to cater for all kinds of buggy software...
