On the contrary, redundancy implies more work somewhere: e.g. more work
for the parser, more effort needed by the python-dev crew, bigger
binaries, larger code bases, more complex test suites, slower development,
longer downloads. Whatever the nature of the redundant thing, there will
be a cost to it. If that cost isn't outweighed by some advantage it should
be eliminated merely because it is redundant and therefore a cost we could
do without.

I suppose, theoretically, if you could find some cost-free redundancy,
something that just happened for free, we would have no reason to care
whether it existed or not. But since cost-free redundancies don't exist,
or at least are very rare, we should prefer to remove redundancies UNLESS
they offer some advantage.
