"Because quite simply put: you don't seem to understand the difference between an SVG image and a non-SVG image wrapped in SVG image tags. GG's books validates with no errors because it does not include any images in the SVG format."

Just to try and be clearer, whenever I talk about svg format I'm really talking about using svg wrappers around jpeg images. Perhaps I caused some confusion by saying svg format but my only reason for doing that was to save some space. After all, this is a blog where abbreviations and short cuts are commonly used to save space. In future I will always refer to such images as images with an svg wrapper to help avoid any misunderstandings.

"As far as the rest goes: I think you're taking a few liberties with regard to the Kindle Publishing Guidelines. That's certainly your choice. But you should probably make it clear that your plugin is not really any kind of true KDP specification validation. It is a plugin that checks for what you personally have decided is good enough for your own KDP uploads."

It might seem that I'm taking liberties with the Kindle Guidelines but I have also given some good examples of gaping information holes and lack of doc updates in the Kindle Guidelines in my posts above. But, like you say, I guess that it's really up to each individual indie author to find this out for himself. Personally I agree with st_albert -- the Kindle Guidelines is a poorly maintained document.

"Regardless of if they're "outdated" or bit ambiguous in spots, it's a bit of a stretch to ignore Kindle Publishing strictures simply based on anecdotal "works for me"s (in a KDP Validation Plugin). Validation is almost never about what "might sometimes work with no problems." It's about setting a baseline that people can then choose to ignore at their own peril--knowledgeable in the fact that "seems to be working" isn't at all the same thing as "valid."

You're not wrong about the "works for me" part. But if you can point me to the detailed Kindle Guidelines for correctly formatting the Look Inside version of my ebook, I would be very grateful for that information. Unfortunately, the Kindle Guidelines gives no information at all on how to properly format the Look Inside version. That information should be in the Kindle Guidelines because it is important. Why isn't it there? So all I can do is try and find a successful way to do it for myself which is what I've done over the years. And if people think that my info is taking a bit of liberty and a load of bunk then that's fair enough. My only intention is to pass on some useful information to other authors/formatters that is not in the Kindle Guidelines. But really, the best person for you to ask whether the Kindle Guidelines is up to date and accurate is Hitch. She has also, on occasion, expressed some considerable frustration with info holes and lack of guideline updates in the KDP forum. So best to ask Hitch because she's the real expert in this area.
