Is there some deeper reason we're not using code that looks like this?

The current ‘interactive’ form supplies DIR and DEFAULT-FILENAME args to
‘read-file-name’ if the current buffer is Emacs Lisp (ish).  Those are
available to the user via ‘M-n’.
Why is that useful?

Because you can compile the current buffer's file by just hitting RET.

Sure, but that also works without the file-dir and file-name parameters being passed at all.
