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/

if someone has the energy to migrate from C++ to C++2, then it’s just better migrating to rust

C++2 is just syntax, really. There is no borrow checker. There is no new standard library. No FFI.

Yeah, these are large levels of difference, like from a -> b vs a -> o. Additionally anything written for cppfront can be trivially transpiled back to plain C++, meaning you lose nothing if you decide to abandon cppfront in the future.

Indeed. One of the simple but effective features that it has is that a compiler can easily see what is in new syntax and what in old one, and as such, it can make different assumptions.
