What is your opinion about SVG color gradients?

Do we need to consider a more complex color structure with full
description of color gradients?
Or, alternatively, should we reference color gradients by an index
within FT_Color?

I think this feature was added to support COLR/CPAL fonts, which only have flat colors; the only use for gradients would thus be proper SVG. Given the complexity of SVG I don't think it's a good idea to attempt to decompose it into a set of shape layers with gradient descriptions. I think applications would rather consume the SVG directly.
