So? ps2pdf exists. It's not like it isn't already part of our toolkit,
so I don't see the problem with using it for creating a vector format.
pdftocairo can create an SVG from that, for example.
Read the question again. It was about outputting L

My uneducated guess would be that with Cairo etc.,
it might be more natural/easy to import vector graphics in SVG format
than in EPS?
Yes, I think. Basically, we could support embedding PDFs via Poppler,
or SVGs via librsvg.
It would be nice to have both, but I really think at least one of them

t would be including a publisher's logo, for
instance.
A logo will occupy a small fraction of the page. Do you really need to
have it in such high resolution that the file size becomes a problem?

And apparently tools such as Inkscape offer EPS to SVG conversion

Zero. PostScript is a full-fledged programming language. See the
size of GhostScript,
t would be including a publisher's logo, for instance.

I am not at all convinced by these workarounds just to get Cairo a bit
earlier and avoid walking the proper road to the clean solution (ie
properly deprecating what we don't want to or cannot support).
\postscript can be deprecated on other grounds, but we cannot
really deprecate \ep
