which 'other' rules can/should be sa-compiled?

[snowcrash+sa]

i currently use a cron job to

  sa-update --channelfile /usr/local/etc/sa/update-DIST-ch.conf
  sa-update --channelfile /usr/local/etc/sa/update-SARE-ch.conf

pulling updates, as available, into my system-wide rules update directory.

if updates exist, then i compile them,

        sa-compile --sudo -D

resulting in compiled rules that override the non-compiled distro'd files.

works fine here.  and, i /think/ is the generally intended (?)
behavior of sa-compile'ing.

question:

        any reason NOT to ALSO compile other, non-SA/SARE rules?

e.g., FuzzyOcr could benefit from a performance boost.  just not clear
to me if it can be compiled, or benefit if it does.

comments?

thanks.
