Summary: This feature was only used in two places, but contributed a non-trivial amount to the complexity of RecursiveASTVisitor, and was buggy (see my recent patches where I was fixing the bugs that I noticed). I don't think the convenience benefit of this feature is worth the complexity. Besides complexity, another issue with the current state of RecursiveASTVisitor is the non-uniformity in how it handles different AST nodes. All AST nodes follow a regular pattern, but operators are special -- and this special behavior not documented. Correct usage of RecursiveASTVisitor relies on shadowing member functions with specific names and signatures. Near misses don't cause any compile-time errors, incorrectly named or typed methods are just silently ignored. Therefore, predictability of RecursiveASTVisitor API is quite important. This change reduces the size of the `clang` binary by 38 KB (0.2%) in release mode, and by 7 MB (0.3%) in debug mode. The `clang-tidy` binary is reduced by 205 KB (0.3%) in release mode, and by 5 MB (0.4%) in debug mode. I don't think these code size improvements are significant enough to justify this change on its own (for me, the primary motivation is reducing code complexity), but they I think are a nice side-effect.
