The only mandatory fields in that form are the rustc version (that's printed as part of the error) and the backtrace. The file being generated includes both of those things.

> Asking to clarify; I think you might be suggesting to reduce to the form just being "got a ICE? paste your error here and hit submit" which would be good

I would do that once the new ICE storage mechanism is exercised enough for everyone to be confident in its behavior and enabled in the stable channel.
