I'm not the only epub creator that uses SVG in epubs. I certainly don't think because I put SVG images in my own epubs I'm personally going to have any effect on non-compliant reading systems. However, if epub authors use features in the spec like SVG, users will aggregate toward reading systems which support those features - in this case ones which display the images. Non-compliant systems will need to either support the features or lose their user base over time.

There are things an author can do to work around things in non-compliant systems like using alt text or <object> tabs, but support for those workarounds are spotty.

The most popular reading systems are all compliant btw, last I checked the ones not supporting SVG are Stanza, Aldiko, and the Firefox EpubReader plugin. Stanza is already losing it's userbase since the Amazon acquisition and launch of iBooks. On the Android side I'd love to see Aldiko start supporting SVG. Working around non-compliant systems problems by not using SVG is definitely not going to help make those reading systems more compliant, it's just going to allow them to continue to be mediocre....

It's not like I'm arguing for the use of obscure epub features which all of the reading systems have implemented poorly, SVG is very useful and well implemented across most systems.

Edit: can't recall for certain whether or not Aldiko supports SVG.
