Two good points. Both can be achieved with general-purpose
compression algorithms, slightly adapted. However, having to tweak
the available libraries sort of misses the point of using standard
algorithms in the first place.

I'm quite willing to believe this. However, I'd be surprised if the
difference were significant (as in: more than a handful of percent
with four fingers chopped off).
