This would constrain us to have a different SQLSTATE for every error
message, which we aren't going to do.  See elsewhere in thread.  It's
also unclear how you insert parameters into error strings if you do this.

I am not really concerned about shaving bytes transmitted for an error
condition.  If that's a performance-critical path for your app, you need
to rewrite the app ;-)

And you put it where, instead?

The existing scheme for localization works fine AFAICT.  I don't have
any interest in reinventing it (nor any chance of getting this done for
7.4, if I were to try...)
