RE: Canvas Test Submission approval/feedback request

It combines simple SVG support with canvas's drawImage. 
Surely you don't expect the SVG WG to start to write canvas tests.

The SVG image is very simple - not exotic specifically so that it's not testing the actual SVG implementation.

Strictly speaking, that seems to be a conformance criterion of SVG 1.1, not of HTML. Therefore the SVG testsuite would be the right place to test it. As far as I can tell HTML 5 does not require SVG support and the references to SVG are to SVG 1.2 Tiny. Unless I am overlooking something, SVG 1.2 Tiny omits the conformance criterion that you mention.

As a practical matter it may sometimes be necessary to go beyond the letter of the spec where it does not require support for specific formats e.g. it is hard to test video without assuming some set of possible codecs. It is unclear that this is such a case.
