The missing bit here is how often this happens.
Once you did an actual "git gc", your repository is stored in a single pack file, and only new files are stored unpacked or in separate packs. Subsequent "git gc --auto" will just pack unpacked objects together by groups of approximately "gc.auto" (i.e. 6700), which is quick, until you reach "gc.packlimit" (i.e. 50). You'll trigger an expansive repack only after that. So, roughly, you'll get an expansive repack after creating 300,000 object files (unless you ran "git gc" in the meantime). Unless you do very nasty things with your repo, that really means "not often", and especially "not often enough that you should care" in 99.9% cases.
