The reasons come down to making the process look different to ps or similar tools, whether to remove path information, indicate process state, hide the real process name for (weak) security reasons, or make a process reveal its real purpose. In the latter case, I mean changing an interpreter's argv to something that relates to the script it is interpreting.
Perl allows modifying $0 for example, on many platforms anyway.
None of the foregoing necessarily justifies allowing such manipulation in the Process library.
