And that's a specific problem to 5e, not a problem with Half-Elf as a whole.Even the 2014 Half Elf is fluff. Once the Abilities relocated to background, there is no Half Elf mechanics except extra proficiencies, which is the same thing as an extra background feat.
There is negligible loss when deleting Half Elf mechanics. The Half Elf flavor remains in full force.
The 5e half-elf is half-human, which basically means 50% of its constituent parts don't exist.
5e human has even less than half-elf. Should we remove humans from 5.5e too? ASIs, feats, and languages are now background, so 100% of what makes up a 5e human got moved there.
