Probably, but note that Google says they are they main customer anyway, and it is an experiment above anything else. Anyone that can reach out to Rust, Go, Java, C#, whatever, should do that preferably. There are also some efforts to tame existing C++ with profiles, and replacing UB with erroneous behaviour, and that's about it.
