After playing with test repo a while it seems that "git gc" never touches pack files which have accompanying .keep file around. (And it's common to have a .keep file after "git clone".) This makes gc perform faster. A side effect seems to be that objects which later become unreferenced in those pack-files-with-.keep are never pruned. *.keep files also seem to prevent from really aggressively optimizing the repository's size.

Probably a crazy idea: What if "gc --aggressive" first removed *.keep files and after packing and garbage-collecting and whatever it does it would add a .keep file for the newly created pack?
