This. Eldritch actually means odd or macabre, not necessarily magic.Eldritch blast and Eldritch Giants existed in 3E, too. I'm also pretty sure that it isn't necessarily meant to be a synonym for magic, but an adjective to describe powers and creatures that are otherworldly or alien in origin.
As a side note, arcane is not a synonym for "magical", but instead closer to "unknowable", "unnecessarily complex" or "esoteric." It has frequently been said that the full rules of baseball are rather arcane.
