Dynamic linking also allows for extensible applications that have to otherwise be implemented with slower OS IPC calls, and higher resource costs in process and CPU cores management.

Which also prevents good privilege separation/sandboxing. See PAM vs BSD Auth, where the former cannot be secured with anything like pledge/unveil or Capsicum, but the latter can.

True, the question is if everyone is willing to accept the higher resource costs in process and CPU cores management to make it a non-issue.

Which given the mikrokernel hate in some circles, doesn't seem like it.
