RMS primarily uses C and Lisp. Lisp source code is a tree already. And C is so simple you can get by with tags and such.

If he was a C++/Java/C# programmer (which he is not) he may have a different feeling on the importance of the AST relative to the risk of Microsoft using gcc with VisualStuio to offer advanced features while by-passing the GPL.

Of course, but even with lisp you can't (programmatically) work on the code without having that code representation. If it's trivial, then there's no harm in opening it, but RMS thinks otherwise, so there must be something else.
