nord-gedit should support xed and pluma.

[Hebgbs]

I built the AUR package for nord-gedit without the gedit requirement and it shows up in xed just fine because xed is based on gedit.

pluma, the text editor for MATE also is based on gedit.

I don't know how to resolve this in a sensible manner, but I am sure you can find a way. Since xed and pluma pulls from the same location as gedit for themes, I don't see why gedit is a hard requirement to install this beyond name.
