I agree in theory, but in practicality I don't. ∆ and δ have distinct and separate meanings in some of my coursework that can't be exchanged. The nomenclature/symbolism is so screwed up in some engineering fields that it would either require all students to revert to the existing symbolism or a level of investment in rewriting literature from research academics that created this screwed system in the first place. I think Feynman had it right, he could invent the best symbols in the world for every operation but no one will use them.
