That's certainly true.  On the other hand, I'd really like to see a
version of the oops-as-QR-code bits that uses VGA block characters to
work in non-graphics, non-framebuffer mode, which would require fitting
in at most 80x50 (using the half-block characters).  That wouldn't allow
nearly as much data, but likely enough for a somewhat useful crash
report, especially in aggregate.
