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?

The first method is far more difficult."   ― C.A.R. Hoare
