Here's an example. This tent is not in production anymore, but was sold without poles. UL-hiking often involves finding as many uses as possible for as few items as possible.

Sibling comment gives a good example. I happen to have a Durston Gear XMid 2p: https://durstongear.com/products/x-mid-2-tent-ultralight-bac... .

Some tents are designed to use your hiking poles in place of some or all of the poles they would normally use. Get double duty out of the mass you carry. If you're going to carry it hundreds or thousands of miles weight becomes very important.
