Yeah, sorry about spreading that confusion.

FWIW I've been running a combination of these two at work (also keeping
the big pack), and they've had a sizable impact on packing our monorepo,
on one of our dev boxes on a real-world checkout with a combo of the
"base" pack and other packs + loose objects, as measured by
/usr/bin/time
* Reduction in user time by 37%
* Reduction in system time by 84%
* Reduction in RSS by 61%
* Reduction in page faults by 58% & 94% (time(1) reports two different numbers)
* Reduction in the I of I/O by 58%
* Reduction in the O of I/O by 94%
