Hi, everyone!

Hoping someone can point me in the right direction, or confirm this isn't possible.

Given this SVG (which renders as text-on-path, meaning the text's baseline is the defined path):

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 872.55 872.55">
<path id="signaturePath" fill="none" stroke="none" d="M117,435a318,318 0 1,0 636,0a318,318 0 1,0 -636,0" />
<text style='font-size: 1.25em; opacity: 0.75; font-family: monospace;'>
<textPath href="#signaturePath" startOffset='15%'>
SOME TEXT HERE
</textPath>
</text>
</svg>

I'd like to, using the command-line convert the text to paths:
inkscape --export-plain-svg=converted.svg --export-text-to-path curveText.svg

Unfortunately, while this does convert the text to paths, it does not keep the text placed ON the path; it just outputs paths in a straight line.

Is the desired result achievable?
