Regarding the closure size, the top packages and the usual suspects:

There’s a preliminary patch to improve the LLVM situation at
<https://issues.guix.gnu.org/42576>.  I’m sure we can also do a better
job on the size of those other things.

A bit of a shame that mozjs shows up here; that’s because of Polkit:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix graph --path ktouch mozjs <at> 60 -t references
/gnu/store/179ifxjb2kvapzydsnkh2vylhnx79kkk-ktouch-20.12.1

/gnu/store/a5m2xzsv3ff1gsh4pkdxbv99nchmlkhq-mozjs-60.2.3-2
--8<---------------cut here---------------end--------------->8---

(It’ll be worse when Polkit depends on Rust…)
