Can you find a reason to exclude

&x / &x' = sqrt(-1)

as a legit transformation coefficient?

I'm sure that it's possible to work perfectly well with
complex coordinates.

That's what a (+---) signature is.

But the notion of a metric "signature"
only makes sense if the coordinates are real.

I don't know what "makes sense" means, but
I prefer to use a (++++) signature BUT that's
choice not a physical law of nature.
