I think it depends on the context. In open source software, the
history is quite important - when I digged into distutils, I wished
svn were better at this to understand where some code came from (the
information is almost always lost when changes cross files). In a
company, or more exactly when people working on the code are
physically near from each other, you (hopefully) have people who know
a lot of the 'black art' behind things, and who are available to
Concerning branches, he said he had no experience in code review. So
it is to be taken with some perspective.
I think ultimately, only experience can really tell which things are
better than others on those issues.
