Do you mean that fast-import is not a plumbing command?

I'm a little confused by this. Do you mean that a fast-import stream is not allowed to use multiple branches, or that when a fast-import stream represents a commit that changes one file, it needs to list all files rather than the one that changed? Neither is true.

The fast-import tool started as a tool to write objects to pack directly, or in other words to save time by avoiding the step of writing loose objects. That is still one of its main benefits.

Just to be clear, I never said such a thing. :)

Thanks for some useful clarifications. Jonathan
