I'm curious how they define 'low-end device' here if it needs a javascript interpreter to run.
Watching the presentation at https://www.youtube.com/watch?v=27o_f_b1U3Q, it looks more like they're focused on making things like media players and settop boxes than, say, an IoT thermostat. And you'll need a Cortex-A class device or greater running Linux.
I would be interested in knowing about the Sizes of SVG produced by this tool. Some of the SVGs converted by poppler utility tool 'pdftocairo' are just too large i.e few MB's which is absolutely unacceptable as these large SVG'S tends to crash the mobile browsers.
Original PDF - 1.0M, SVGs - 7.7M, gzip'ed SVGs - 1.7M. I think the latter is a preferable format for the web, so you are looking 70% increase for this types of documents, but bare in mind that you may send only certain pages.
