XKCD’s comic on competing standards feels appropriate here:
EdgeQL looks... interesting, but I need to see more to decide for sure. Would be cool if they built out a translator, so you could pass in SQL and get back EdgeQL.
I don't think translating from SQL to take a look at the EdgeQL it produces makes much sense, since it'd result in very unidiomatic queries. SQL prefers joins and flat rows, while EdgeQL is based on following links and has great support for nested data output.
