We can. But I think the result will be git.

Michael Raskin: If you'd prefer a different one say so - and say why,
please. In a previous post I concluded that he would accept using git
as alternative to SVN. See here:

It could be used as additional git mirror for that reason if there is
need to. This could provide some additional transition time for some
users. Is someone interested in it at all?

Is your comparison fair? Did you include the checked out files in the
git calculation?
Because SVN stores all files twice let's add 1/rd of the space of SVN.
Then you have 40M + (130/4M) approx 80MB. Still less than 130MB.
But I expect nixpkgs to grow. So in 10 years svn will be smaller because
it doesn't store history.
