Inkscape probably treats the source SVG differently than an optimized output SVG and includes additional data to make editing the file better. Other apps use a proprietary format for their source files that contains this additional information and have to export to an open format for output.
Probably for copyright and license. It's a common feature, MS Office documents include even more metadata, such as how many times the file has been saved.

My problem isn't with quantity of metadata. It's with personally-identifying data. And I can't imagine what the filepath could ever have to do with copyright or license.
I don't see how this is a common feature at all.
The only way I can reproduce your scenario is by inserting an image using "Link" instead of "Embed".
Other than that, was it part of the original/downloaded file?

You can include links to other resources (e.g., an image) in an SVG file. Perhaps it's meant to help resolve those paths?
Why is it even a "feature" in the first place? It's not the kind of thing I'd expect to even have to worry about whether it defaulted to on or off.
