We revisit the change after LC or CR and take a look at implementations. There actually is a chance that browsers change the behavior. We tested the change in Blink and WebKit. Both have more than 1500 SVG tests. Just one test failed: animate-elem-84-t.svg from the W3C SVG test suite. No authoring tool exports transform functions with wsp after the function ident. So the influence on real world content should be fairly minimal, assuming that the vast majority of SVG files is created with authoring tools. Difference 1), 2) and 3) from my original mail still apply:

 I did the change in CSS Transforms as described above[1]. I removed the issue from Geometry Interfaces.
