Inkscape 1.0.1 is mainly a stability and bugfix release. It also comes with a few new features that hadn't been stable enough to make it into Inkscape 1.0.
Can try to create patch, but a bit later.

Update to 1.0.1, added support of "Color-managed PDF export using Scribus"
New option SCRIBUS add run dependency from print/scribus-devel:
Color-managed PDF export using Scribus
An experimental Scribus PDF export extension has been added. It is available as one of the many export formats in the 'Save as' and 'Save a Copy' dialogs.
To be able to get a correct and color-managed CMYK PDF file with text converted to curves that corresponds to your drawing in Inkscape, you must:
have Scribus 1.5.x installed (the Scribus executable must not be called scribus-ng)
have enabled color management for your document
have selected one color profile to use for the colors in your file
assign all colors in the document with the color managed color selector in the Fill and Stroke dialog
not use filters in your drawing (this includes blur)
not use any transparency if you're exporting to PDF/X-1, PDF/X-3 or PDF 1.3
not include any bitmap images
not use markers
not use any other SVG features that are not supported by Scribus
Tested on 12.1-p10 amd64: make check-plist/install/run.
