Thank you for your confirmation.

To be frank, my POV above is just the impression after a very cursory
glance, so it might be incorrect.

If so, this step will also generate the supported file format by
LaTeX, then all subsequent jobs will be done by graphicx package
normally. So, I suspect that the svg package will invoke the graphicx
package with the above command internally after the supported file
formats have been generated correctly. If this is the logic used by
the above command of svg package, then I can't see we need much job
for writing something like graphicx.el for svg package, I mean, once
the supported file formats has been exported with inkscape, all
subsequent workflows, in essential, will be done by other packages.
But I'm not sure whether this is the internal mechanism of this
command.

OK. But what should we want to do with a svg.el for this case?
