Currently, when you try to save an SVG containing gradients with SVG 1.2 Tiny profile, Illustrator rasterizes the gradient and embeds the rasterized image instead of properly converting it as a pure vector information. This reduces the qualify of the saved image a lot and it's no longer scalable with even further quality reduction.

SVG 1.2 Tiny specification supports gradients and so it would be really helpful if Illustrator kept the vector information from gradient. This is also necessary for BIMI logos (https://bimigroup.org/) as it doesn't support images/links in the SVG.
