HiFiBerry EEPROM purpose

[Wattie]

In layman's terms, what advantages will the EEPROM deliver on add-on cards? Specifically the HiFiBerry DAC+, but I'm happy to try to understand it in a general sense.

The EEPROM can hold the device tree blob that's needed to configure the GPIO pins for the add-on hardware.

So the EEPROM takes the responsibility of introducing the device instead of predicting every possibility on the host side, or the usual configuration requiring a deeper understanding? A bit like coming to a party with your favourite drinks, food and music. I assume it's like plug and play, instead of plug and struggle. Under most circumstances I would only do that once and then leave things alone

Has anybody implemented this yet? Everything I have experience with has required considerable tweaking.
