Could you or others making these kinds of assertions possibly justify them?

They are stated as if they were "self-evident truths".

I used SCCS for over a decade on various flavors of Unix.

CVS was then the new kid on the block, and I used that for a decade and a

Then, SVN, with its very functional tagging and branching system,
