As a consequence, if you use an old version of ConTeXt and you have Inkscape 1.0 or newer installed, the conversion from SVG to PDF fails.
Newer versions of ConTeXt (since the second half of May 7th, 2020) will detect Inkscape's version and manage to convert SVG to PDF anyway.
But it's a temporary workaround, until version 1.0 of Inkscape gets widespread, because version detection has a performance cost.
