Ergo, this application would ironically be non-portable on Linux

Yes, that's true enough, until nobody was using the old versions any more.
If portable Linux applications have to handle the situation using
existing facilities there is absolutely zero value to add it now
because it only will add more complexity to applications handling
things correctly because they will always have two cases to somehow
conditionally handle under Linux.
And if the intention is to just always assume the close() semantic
thing is there, then you have given me a disincentive to ever add the
facility.
If you took that argument to it's logical extreme they you'd never make
any changes that made changes to existing behaviour, and that's patently
not the case.
