Without DT aliases, the numbering of mmc interfaces is unpredictable. Adding them makes it possible to refer to devices consistently. The popular suggestion to use UUIDs obviously doesn't work with a blank device fresh from the factory.
See fa2d0aa96941 "mmc: core: Allow setting slot index via device tree alias" for more discussion.
