Is this a deliberate limitation, or is it just that the base iPhone 15 chip does not include an USB 3.0 controller?

This original source does not say anything about what the phone will support. It is about the charging cable that is included.

It's just the charging cable, it seems it does not have all the wires to support USB 3.

The rumors and articles on this are all over the place. Some are reporting that the non-pro phones will only support USB 2.0 speeds while the pro phones will support faster Thunderbolt.

Others talk about the cables saying that Apple will ship USB-PD (power delivery) cables which are specified as USB 2.0 with all of the phones.

Are the speed limits on the ports or on the cables or both? When these launch there will confusion for several days and perhaps until testers get them in their hands to try different cables.

The included cable will support USB 2.0 no matter which iPhone you buy. Just like with all USB-C MacBooks, iPads, and the vast majority of Android devices. It's a charging cable, after all.

The capabilities of the port itself may vary depending on which iPhone model you buy, with the iPhone 15 Pro supporting Thunderbolt/USB4.

I imagine it’s just the chip. It would be really weird if features like (wired) Continuity Camera just stopped working.

This is only about the included charging cable. What the iPhone 15 itself will support remains to be seen.
