I (personally) have no plans to change it.  If I remember correctly,
Bud Brown came up with an alternate scheme, but the imported data from
the kernel proper required to accomplish it was enormous (bordering
on absurd), so I suggested that it would be more appropriate as an
extension module.

Bud -- feel free to chime in here...  ;-)

For that matter, even the "old" way required the import of ~1000 lines
of kernel #define's -- which always bugged me -- and was pretty much the
only crash command that had to do such a thing.
