If you mean that there should be new syntax for setting header arguments
on a file or sub-tree basis w/o using file local variables, I'd be happy
to apply a patch.

If you can think of a clean way to implement this then we should go for
it. I doubt many existing configurations rely on this behavior.

Clearly this portion of the manual should be improved.

Every language can specify default header arguments through setting a
defvar. The syntax is `org-babel-default-header-args:lang'. This
should not be hard to find through apropos, simple tab completion or
searching the archives of this mailing list. However I agree the manual
should be improved wrt this topic.
