I would not remove it as even I have some org files using them - shame
on me.
But what about making it user configurable? a variable
~org-babel-tangle-use-deprecated-header-args~ which if set to non-nil would
enable this additional code, if nil it would be skipped? The default
should be set to ~t~ to be backward compatible.
