Go messages are harder for both devs and users to read. Grepping for an error message in a codebase is a special hell. Besides, it's quite trivial to simply return the exception's getMessage in a popup for an okay-ish error message (but writing a stacktrace prettifier that writes out the caused by exception's message as well is trivial, and you can install exception handlers at an appropriate level, unlike the inexpensibility of error values)
