I don't dislike sysconfig-hardware, per se, but I do dislike the lack
of documentation.  It was apparently written by SUSE.  They used it
themselves for a while, then abandoned it.  (I don't know what they
put in its place.)  Furthermore, the version we use differs from the
version SUSE last used in several ways, including naming conventions.
So for all practical purposes, Debian is now its own "upstream" for
sysconfig-hardware.  So we can do whatever we want to with it.

No.  The hook script was written by me years ago, and I put it in the
bug report, but it was never incorporated into the official package.

I agree.
