... whether there is any good reason plain {} doesn't generate () (an 
empty sequence)?

I'm not aware that the idea has ever been proposed and discussed in the 
WG. I've no idea whether it would find favour. Probably not; minor 
tweaking for minor usability benefits doesn't usually attract much 
enthusiasm. You might find someone in the WG has grand ideas to use the 
same syntax for something else, like an empty map or array, and wants to 
hold it in reserve for that, and on past experience that would probably 
win the argument.
