SVG Export stroke width

When I export curves, I need stroke width of 0.
Not hairline, a hairline is 0.24.
No print is also not an option, as this gives no output.

How can I have a stroke width of 0 or none?

Of course I can open a SVG in a text editor and change the stroke width.
Acceptable on a single file.
But not for a bunch of files and not as a final solution.

Perhaps @pascal has an idea?
