Please note though, that in case it is sanitized to black, the material.diffusedColor/albedoColor should take over for areas with alpha 0, because diffused Texture with transparent area is the only way to overlay logo for product configurators, without resorting to decal or custom shader code.
This is the use case I have, and many people have been asking questions about similar logo feature in the forum.
No hurry at all
