I know of use cases where the index weighs 300MB, and falling back to
reading it directly *really* hurts.

For crying out loud, what do you store in that repo? What I have in
mind for all these works are indexes in 10MB range, or maybe 50MB max.

Welcome to the real world.

Very unscientifically, git.git index is about 274kb and contains ~3000
entries, so 94 bytes per entry on average.

In terms of software projects' size, git.git is but a toy. Most developers
deal with vastly larger (and often messier) repositories. This is
especially true outside Open Source. Even the Linux kernel's repository is
*tiny* compared to real-world repositories.

I am sure that David could tell many a tale about repository/working
directory size, too.

So yeah, this is the challenge: to make Git work at real-world scale
(didn't we hear a lot about this at the latest Git Merge?)

Ciao,
Dscho
