Having both symbols is useful.
For example I want to say that

 a = +- i
 b = -+ i

The important consequence is that although the actual
signs might not be known, they must be opposite for
a and b.

Yes, I use Postscript output. As far as I understood
from Werner's reply, this symbol is now available via
the PS driver.
