This hoists all the annoyance of figuring out the current pixel's input attachment coordinates to the driver. The pass still deals with all the annoyance of turning an image instruciton into a texture instruction but it gives the driver more control over the position. For most drivers, this will be something like ivec3(int(gl_FragCoord.xy), gl_Layer) or similar, some drivers need something more nuanced. Turnip, for instance, needs unscaled coordinates for some attachments and NVK doesn't really want gl_Layer or gl_ViewIndex for the layer. It's better to just have a new system value that drivers can make what they want.
