It seems like best results for SVG require installing inkscape and modifying 
magick delegates.xml to work with the options supported by the installed release.

As magick appears to be ~6MB including core DLLs, and inkscape is a GUI >120MB, 
making it a dependency seems unrealistic, but maybe optional for serious users, 
and a b-r for config, building, and testing?
[I have unifont whose tools require b-r tex{live,info{,-tex}}, and lesspipe 
seems to b-r all packages which include text converters including texlive, 
although optional depending on user's needs!]

Also note that `convert` as shell or `magick` command should be dropped, and 
just `magick` used instead with current release as it produces an alarming 
WARNING message, although conversions proceed okay.
