Unfortunately this is not too surprising for me.

No it's worse than that. The capabilities of an SVG font are much
greater than the capabilities of a PDF font. Each glyph can at least in
theory make use of all of the features of SVG, multiple colors, stroking,
filters, animation... (I don't think we support animated fonts BTW, but
the spec does). So there is no usage of PDF fonts when you use an SVG
Font, we simply draw the text (character) content in the PDF. So if
'e' is present a bazillion times in the document there will be a
bazillion copies of the data for the 'e' glyph.

This won't help the file size problem.
