Could you elaborate on how the question should have been
phrased in your opinion? I don't understand this from the
following sentences.

(For what it's worth, it was not a surprise to me, as it
confirms my own experience.)

The Inkscape problem looks quite silly,

I think the easiest route is "ps2pdf -dEPSCrop" then
"pdftocairo -svg" (i.e., GS, then Poppler).

PDF may be closer to EPS, but EPS is uncommon today, so I
don't think this adds much value.
