Quotas aren't very useful any more, what
with most systems being either
single-user clients or servers with no need for privilege separation
other than root/non-root. Unless you are using mandatory access
control, which has never been a standard part of any Unix-like system, I
see no reason to continue to forbid changes of ownership.
I think such a drastic change in semantics is bound to violate
some security assumption of some software.
For example, some program might have you create a file
and use your ownership of that file as proof of your
authorization.
