I think we're both talking about the same feature - I couldn't remember
the exact technical term used for Go.

Personally, I don't think tha the check and associated warning brings
anything extra. Getting a cryptic warning about some frame being inner
than another never really helped me more than getting a botched backtrace.
On the other hand, determining that a frame fails that invariant should
be relatively straightforward, thanks to the "info frame" command. Hence
the suggest to toss the check.

But if people prefer to keep the check, and have a technical way of
handling this sort of issue, then why not.
