To be more precise the situation as I tested now is

processing of PostScript specials is disabled (Ghostscript not found)

which means it is always possible to use option 

--libgs=filename          set name of Ghostscript shared library


I had forgotten this since last year. (and as I use MacPorts version)

Thus it is possible to use the TL2019 shipped dvisvgm
on legacy Mac OS with Postscript via --libgs,

But I don't know the Windows situation which was my main 
question on behalf of my correspondant,

And would TeXLive consider shipping fully enabled dvisvgm
or are there technical obstacles related to Ghostscript?

Best,
