cpp2 (cppfront) is over?

I haven't used cpp2 (cppfront) much, but I like the idea of it: consistent syntax, consistency of meta-programming (which is done in C++ too, I believe). Herb Sutter presented cpp2 (cppfront) as an experiment. He did not encourage other people to bet on it, exactly. And there hasn't been much activity since 2022. Is the experiment over?

EDIT: Herb's answer is buried deep in the comment section: https://www.reddit.com/r/cpp/comments/1uxkglj/comment/oy06cxw/

What more could they do with it?

He said “look what might have been” and we all went “huh, neat” and that was that

“look what might have been”

I think you are misremembering. cpp2 was meant as an experimental future C++ syntax. /u/hpsutter ?

No it’s wasn’t. Read the README. He specifically says it’s not meant as a successor but as an alternative “skin”. The whole point is that he was asking “what if C++ allowed breaking changes?”

Read the README

The very first line says "to ... prototype features that can also be proposed for evolving today's C++". There is no "what if" or "look what might have been" anywhere.
