The “Submitting Patches” section mentions closure size specifically.  Is
there anything you think we should add there?

‘guix size’ is key here: it’s a profiler, exactly what we need IMO.
WDYT?

A few years back we were doing better because we used separate outputs
in key places where Nixpkgs didn’t.  Later on Nixpkgs had a large part
of its packages split in several outputs (more than we do).  From what I
heard, it wasn’t as fruitful as they had hoped it would be in terms of
closure size, but it might still be better than what we have, dunno.

The thing is, I think it’s something that requires constant care, every
time we add a package or modify an existing one.  It’s very easy to lose
benefits that had been previously obtained through hard work!

At any rate, I agree we need to improve!
