Alternative libraries in future development?

Hi

I just wanted to know if there is discussion/evaluation of using more alternative libraries (other than musl libc) in future versions of Alpine linux?

For example, LLVM libc++ rather than libstdc++

Another (possibly) interesting library replacement would be netbsd-curses rather than ncurses
