C/C++ sucks to write dev tooling (e.g. syntax highlighting, LSPs, static analyzers) for. Pretty much everyone leans on libclang for parsing because very few people are insane enough to try to reimplement a parser themselves, let alone all the GNU extensions. And even then, macros make robust parsing really difficult. Imagine trying to parse a file that contains two programming languages that can be arbitrarily interleaved at almost the character level. That's basically what C/C++ are.
