This is pretty simple end effective already in AP, just go to stroke and fill in the top left with the object selected and set them to nothing or play around until you get what you are looking for. I honestly don't see a need for a change.

Yep. Would love this.

I know Affinity Photo is a raster program and can only select whole pixels but never had this problem with PS. I shift drag out an elliptical marquee tool circle and end up with something pretty rough looking with some odd flat edges, this is even more apparent when I outline the selection. I'm working on both 300dpi & 72dpi documents and it makes no difference, I have antialias checked, not sure what else to try. I've got to produce pixel-perfect artwork for cinema posters so can't have jaggedy bits. Any help appreciated
