> @fantasai suggested that maybe we could still fix this, and just special-case transparent to normally resolve directly to #0000, but let gradients key off of it specially and do the no-color-change behavior. 

That sounds tricky to explain in a spec, but would map better to underlying libraries. Premultiplication suffers from erosion of resolution (effective number of bits) unless calculations are done in an elevated bit depth, which most graphics libraries don't.
