You can't make pattern swatches with gradients in them. This limitation probably made a lot of sense back in 1996 when gradients were new and complicated. Does it still make sense in 2024, with thirty years of CPU manufacturers fighting to keep Moore's Law valid?

You can't apply a gradient stroke to an art/pattern/scatter brush. Again, this limitation probably made sense back in 2012 when gradient strokes were added to Illustrator. Does it still make sense in 2024?

I'm pretty tired of working around both of these limitations.
