Since the URL to the raw mapping is not in the error and requires external knowledge and the parameters are in free form in the error message I doubt this can become a standard of any sorts. The correct place for this would have been something like sourcemaps.

Yea, this is clearly not enough to be a standard but we don't really know of a standard for this and it is not really our primary expertise.

If Sentry or others that understand this problem space better create a standard format, we would be happy to switch to that.

Everything have to start somewhere. :)
