Is there a way to use other attributes of the the SVG rectangle, such as "rx?"

Are the other attributes listed here possible? For instance, rounded corners?

No rounded corner support as such but one can create any custom path to draw rounded rectangle.
That's what excalidraw.com does for it's rounded rectangles

Ok. gotcha.

I'm reopening the issue - to consider adding this feature.
