While C++ programmers should try and avoid the preprocessor as much as possible, sometimes it just isn't possible to do so. There's just no other way to generate code sometimes. I know, I've tried.
In what case is this true? If it is only to avoid some boiler plate then it is not a good excuse, IMO. You can usually avoid macros by restructuring composition (using multiple layers of templates).
Anyway, cpp is a separate language from c++ so it only affects AST related tooling that modify source files where macros are present. It is overall more separate than builtin textual substitution (which is generally a bad idea) since it is a discrete independent step that a tool easily can apply before analysis.
