Could you say a bit more about why they \left( and \right) aren't really needed here? According to the "book" it should be fine to use them.

@MarcvanDongen, \left\right has two functions, they allow the operators to stretch (but in most cases no stretching was happening in this example) but the second function is that it makes the subterm a \mathinner atom and that gets additional white space in many contexts. Presumably Knuth preferred this in some contexts, but the OP was specifically asking not to get that space and so not generating mathinner atoms is the answer

Thanks. I've never seen this expained in any documentation (but I may have missed it). I did notice Werner's answer touches it.
