3. We can't replicate it as readily in the regular REPL, since that runs Python code directly in the current process, but even there I believe we could potentially trigger a full process restart via execve (or the C++ style _execve on Windows)
This exact problem is solved rather elegantly in Julia. When you upgrade a package that is already loaded in the REPL, it prints a warning: "The following packages have been updated but were already imported: ... Restart Julia to use the updated versions." listing the affected packages. See <https://github.com/JuliaLang/julia/blob/19921aa00468edf11f3d61f8c9b8d639ec71...>.
