It's not that it can't do anything, it's that you have to actually implement things at a lower level. I mean, Gatsby doesn't have any backend CMS out of the box so that's the most obvious thing. If you want to use Gatsby for clients who want to be able to manage their content, you have to select and integrate one.

But even for me, who doesn't need a backend GUI stuff like a contact form was a pain. Luckily I host with Netlify and they have an easy form solution but imagine that across many other situations even for a somewhat simple site. Now you're having to set up accounts with all these other services when before it was all contained in one place. All for what? The benefit doesn't seem substantial enough to me to give all of that up.

Even if you use WordPress as the backend, you've still got to deal with integrating it's API which is more work than something generating all the markup you need etc...
