But yes, even if we accept that simply setting some attributes for a new process is enough (as opposed to running more complex logic requiring an already created process, which is possible with fork()), having a fixed of them for an evolving entity is problematic, more so since on Linux posix_spawn() implementations are developed separately from the kernel.  https://www.austingroupbugs.net/view.php?id=1044
