Yes, it would be more consistent, but that's exactly what it does
currently.  At least, that's what a quick test under Linux shows.

That's surprising.  On which operating system do you see this
behavior?  The treatment of argv[0] in C w.r.t. #! scripts differs
between various versions of Unix, but we tried to compensate for this
in the OCaml bytecode interpreter.
