The acceptance criteria is purely subjective on my part, so there are
no set guidelines as to what is "good enough" to be accepted.  

However, please consider that the last time a new command was added to
the crash utility was the "extend" command back in August 2001.  

The extension module facility was added so that users could write their
own commands for whatever private purposes they were working on without
having to re-patch the base crash utility each time a new version came
out.  And at the same time the base crash utility could remain simpler
and more maintainable, while affording the flexibility to those who are
inclined to write their own commands.
