It explicitly says this, though:

> while much of that build time is attributable to Nix's way of building dependencies

And that part just doesn't make sense to me. I can't see any way in which specifically Nix's way of building dependencies would contribute to this. The compiling of the universe, sure, but then why mention Nix?

It does say that, but it's off in its own clause, then shifts focus away from it towards what seems like the focus of the auditors.
