As long as they are topical and not distracting the hero images are just there to let you know you are on the right tab. I'd prefer one included by any means as it can show a bit of extra effort in curating that image. I wouldn't want to see images just auto generated in the next.js markdown to html build step from the post's tags (like stock images used to be summoned code-monitor-out-of-focus.jpg) though I'm sure that's going to be a thing.
