Yes, and that is my main concern.  I was hoping we could find an easy fix,
though I could not see one.

Well, let's wait until we know we won't change it.  But if it remains, then
yes, absolutely.

Basically, it would say as Matthias noted: do not use ^, and do not check
for anything after the warning (i.e., for the line number, etc.), and if
you do, then do not assume any certain text or lack of it between the
warning and what comes after it.
