What is the difference between ESP8266 and ESP8089? In the block diagram they look same. They both have CPU which means they have microcontrollers, right?

By the description: "Two legs, two arms, a head and a body" we humans also look the same.

If, for starters, I look at the pin-count, I can see the 8089 has limited I/O compared to the 8266, which isn't a bad thing per se, but to say they look the same?
The block diagram of a PC and a Apple machine also look the same, but they're two entirely different species.

The hardware actually seems to be identical, at least this ESP8266 die is labeled ESP8089:

Like that article states: the difference is most likely just the internal ROM and packaging.
You can actually use an ESP8266 as ESP8089: https://hackaday.io/project/8678-rpi-wifi

Forgive me as I have been spending alot of time trying to understand the difference between these two chips. It is a bit confusing since they both use the same die. If all that is different is the ROM and packaging would it be possible to flash a different ROM to make it operate closer to an ESP8266? I understand it has limited I/O. My application doesn't need audio or video so I can live with some basic I/O functionality.
