Re-reading the thread, I can't see where that was mentioned.

But yes, if some boards (still) need that, and have more than one
possible .dtb, the board can't set an OF_LIST different from the default
consisting of DEFAULT_DEVICE_TREE because changing OF_LIST requires
SPL_LOAD_FIT || MULTI_DTB_FIT.

How do we figure out if such boards even exist?
