No, my understanding of .Net core is that this is also the way they want to get back on devices. I think Xamarin will ultimately be based on .net Core. And for a mobile app, you bet you need a way to manipulate images.
Even for websites, depends on what sort of websites you do, but I often need to display charts, so being able to generate images on the fly.
Why are you generating images on the fly to display a chart? Why not send the data points and render a chart clientside using JavaScript? There are plenty of libraries for that.
A lot of clients want native PDF output for their reports. None of the PDF generating libraries I know of support running JS. So if you want the same charts in both, you need to generate the images server side.
I am sure there are other ways but I found using the native datavisualization library very useful and simple to use. I am one of these guys who do as little javascript as necessary.
If you want to draw the chart from scratch perhaps but I use a library to generate the chart then send it as an image to the client. Very few lines of code required in .net, no javascript required.
Indeed, but there's still a heavy focus on web applications.
I have written a few commercial cross-platform applications with Xamarin. They deal with images - and System.Drawing would not have been helpful to me. iOS has UIImage and Android has Bitmap.

Isn't SVG or canvas more suitable for that on the web?

You don't need JS to generate SVG server-side either ...
