Looks like it was a spec change: From: JESD84-B50: B.8. Changes from version 4.51 to 5.0 Edit to support Ver.5.0 in EXT_CSD_REV[192] o Note: A host system should work properly considering future eMMC version. For example, a host system is expected not to exit only due to the EXT_CSD_REV[192] value greater than 7 which will be used for next e•MMC revision.” So my guess, in 4.51 or earlier, something said to exit in that situation.
