Kinda like how you'll notice the 262 doesn't have the R4M rockets.
Yup. And the Lancaster doesn't have 8,000 or 12,000 pound cookies. I'm sure there are other examples; my understanding is that play balance is one of the reasons the cannon corsair was perked, lo these many years ago.
And there's always the discussion about why the B-29 doesn't have nukes!
