Do they sell chip-like modules with camera connectors and battery controllers, though? I don't deny that ESP32 modules look like and are soldered as though they were chips, but to me it's clear that GP was mixing up chips (and chip-like modules) with boards.
Espressif sell bare chips, modules with castellations for soldering to a PCB, and complete boards that typically contain a module. Some 3rd-party boards use a bare chip. Some 3rd-party boards also have castellations, as do Picos sold without pre-soldered headers. 3rd-party modules are also a thing.
Here's a pic of a module and several boards that demonstrates all of that.
