I don't think we can go quite that fast - #import is an officially
documented feature of Objective-C.

Whatever "officially" means; the language is not standardized.

In this case, it would mean the document that asserts itself to be
the definitive description of Objective-C, which is Apple's manual.
Removing #import from FSF GCC would be a deliberate departure from
the written description of the language, an unusual step at the
very least.

Does the manual describe what it does?  Could you send me the description?

The manual is on your machine already, PDF and HTML in
/Developer/Documentation/Cocoa/ObjectiveC.  Page 205 of the PDF
file says "identical to #include, except that it won't include the
same file more than once", and that's about it for description.
