And yet that's exactly how a lot of developers use CVS. You can argue 
that some other way is better but when they move from CVS they're 
looking for continuity of productivity which often means not radically 
changing how they work. At least in the short term.

I no longer believe that the Linux kernel developers are the "primary 
audience". They are certainly an important and influential set of Git 
users but there are also a lot of non kernel projects using Git. If not 
now, there will soon be more non kernel Git users than kernel Git users.

[Nice description of how to work with the Linux kernel code base.]

[Nice description of one way a hypothetical project with dependencies on 
libraries under active development could work.]

There's no question that that may be better for some projects. But I 
believe that the project members (or owners) should decide how they use 
their tools.
