- arches using the old frame stuff are typically in worse shape
- arches using the old frame stuff can't use CFI (i.e., can't use
exploit GCC's frame debug info)

the second one in particular is of issue to users - it affects GDB's
ability to do decent backtraces (especially through glibc).

Yes, the list needs updating, SPARC and ARM are done. MIPS and PA are
"done" (it lost the signal stuff). For PPC, that will be 6.2, which
leaves a few strays.
