I'm pretty sure the size would be smaller in git.
Also, git has support for graft-points so you can say, OK, the history
before point X goes into the "foo" repository, and after that we use
"bar" repository. People that don't care about ancient history can
just use "bar" and people that care can have the whole history ("foo"
+ "bar") using a graft-point that joins both of them.
