Wow, @tophf was right! It is possible to manipulate shadow DOM, it's just that this website has some additional funny stuff going on!

I found a random page with #shadow-root (open): https://apearce.github.io/react-shadow-root/

And both those two following lines of code, read and write, did work in console (F12) and in a userscript!

alert('document.querySelector("basic-demo").shadowRoot.querySelector("span").innerText: ' + document.querySelector("basic-demo").shadowRoot.querySelector("span").innerText);
document.querySelector("basic-demo").shadowRoot.querySelector("span").appendChild(document.createTextNode(" toto"));
