Legend
A half elf just becomes a human (or whatever) with an elven lineage, just as an aasimar is a human (or whatever) with celestial lineage. They are not being deleted, they are being simplified.If half-orcs and half-elves are gone in the future, so should aasimars, tieflings, and probably others: just bring in playable celestials and fiends.
That being said, if future editions don't include them, I'll either add them back in (like everything else) or just not play it.
