I agree that creating a "-split" option would be more forward compatible.
I have created this bug to track the "-split" feature:

Hi,
A long time ago, cairo implemented the SVG 1.2 draft with support for
multipage, so pdftocairo complies with that and submits an entire PDF
document to be rendered into 1 SVG file. However, no existing svg
viewer can open these files because SVG 1.2 was never adopted by W3C and
was actually dropped in 2005 in favor of development of SVG 2.0. See
https://www.w3.org/standards/techs/svg#obsolete
Inkscape has scapped their own plans of supporting multi-page SVG since
it's not supported by any current SVG specification, and SVG 2.0 doesn't
look like it will have multi-page either
http://wiki.inkscape.org/wiki/index.php/Multipage
So, I would be willing to prepare a patch to have SVG treated like other
single-page image files, so that calling pdftocairo would generate many
SVG 1.1 files. Libcairo already has a
cairo_svg_surface_restrict_to_version() method.
Would you be interested in such a patch?
I think it would be best to add a "-split" option (applicable to all
vector outputs) for creating one file per page. Changing the default svg
output to one file per page would be a significant change to the
pdftocairo behavior that would break any existing scripts that use
"pdftocairo -svg".
Using a -split option also leaves open the possibility changing the
current multipage svg to whichever multipage option Inkscape chooses to
implement.
We can also change the pdftocairo svg version to 1.1 now that 1.2 is
obsolete.
I suggest creating a bug for this. You can attach patches to the bug or
wait for me to implement it.
