A bot could also allow the use of dynamic linking for libraries and languages that do not have a stable ABI. Haskell, Rust, and OCaml come to mind, as do C++ template libraries when the template part changes. There is simply no way I know of to have a stable ABI in Rust or Haskell, so being able to automatically rebuild reverse dependencies when needed is the only realistic way for them to use dynamic linking at all. In C++ one often gets away without the rebuild, but this is a violation of the One Definition Rule and is undefined behavior. Furthermore, any bug fixes in template code or inline functions will not propagate to users of the library until the users are rebuilt. -- Sincerely, Demi Marie Obenour (she/her/hers)
