> I think a common ground here could be to support signed char and unsigned char explicitly as extensions. But do we agree that std::string<int> makes no sense and if it breaks some users that's fine?

Yes, I'm not worried about other fundamental types; they are much more problematic than `signed char` and `unsigned char` for the reasons you indicated.

> Also, would you have an appetite for reviving https://wg21.link/n1985?

Not really. I could bring it to SG16, but I don't expect it to garner much favor. It might get some points for standardizing existing practice, but I expect the SG16 response to be that we don't want to encourage use of such extensions.
