I think this is a case where consistency is valuable.
And for something like
struct Point { x, y int }
there is no real confusion to writing
Point{1, 2}
Why make people always write
Point(x: 1, y: 2}
?
Also consider that there are useful structs with a single field, in
order to implement some interface without allowing people to casually
change the value. It would be a pain to force people to always state
the field when writing a composite literal. And it would be a pain to
have a special exception for a single field.
