What would you like to see us add to this API? What would you like to see us add to this API?

Add support for the 'advanced polyline' features which were added to the Android and iOS SDKs as announced here.

This functionality allows you to have images along the path of a polyline (StampedPolyline). The current JavaScript API only allows SVG symbols.

It would be helpful of polylines in JS could use the same set of icon options as markers, including images. This would better match the Android / iOS functionality.

What part of the API (please specify, a library, or the code module)?

Polylines

Please describe how the feature should work:

const image = "https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png";
const line = new google.maps.Polyline({
    path: [
      { lat: 22.291, lng: 153.027 },
      { lat: 18.291, lng: 153.027 },
    ],
    icons: [
      {
        icon: image,
        offset: "0%",
      },
      {
        icon: image,
        offset: "50%",
      },
      {
        icon: image,
        offset: "100%",
      },
    ],
    map: map,
  });

Please give a use case or explain where and why you need this feature:

I'd like to render polyline with a repeating image that can't be easily expressed with the existing symbol svg because it needs multiple colors.
