Hi, Mental, Bulia-

Great conversation, and thanks for getting back to real-world use cases. 
  I liked Chris' gradientMesh suggestion, and like Mental I'm not yet 
convinced some variation on it might not be suitable.  But I'm open to 
other suggestions, especially those based on pragmatic experience.

The idea of prototyping the various options strikes me as the best way 
forward, and to come up with a set of end goals we are trying to 
accomplish with the new gradient(s).

Photorealism (or something akin to it) seems to be one use case.  This 
also suggests a nod to 3D-esque textures or shading (I don't want SVG to 
go down the true 3D path).

Bulia, your example seemed to have more in common with filters than it 
did a gradient/affine transformation, so we might consider look at this 
as part of the new Filters spec, as possible variant approach.
