I think we need to think again about this, as it's not only "createTreeWalker", the DOM document has all those createXXXX methods like "createElement", "createAtttribute" ..., and then all those inherited DOMNode interface like "removeChild", "replaceChild" ...etc. If we have to overload each and every method with const modifier, it's not only a tedious work but also PERFORMANCE may impact badly with all these overloaded virtual functions. From my point of view, it just doesn't worth at all. Performance is much more important. I would prefer leave it as is.
