Record Puns/Wildcards

I just noted that code like
my_config = default_config {..} where
name = "my project"
description = "some longer text"
gives me a syntax error, even if I have NamedFieldPuns and RecordWildCards
extensions enabled. It seems that these extensions only work for record
constructors and not for updating values.
Is there a special reason puns/wildcards are not allowed in record updates?
Cheers
Ben
