Another point: having a single “upgrade manifest” probably won’t scale,
first because it takes time to evaluate it (looking for the latest
upstream version of all these packages), second because the jobset will
be messy if it contains tons of unrelated upgrades.

So I’m thinking that probably we’ll want focused upgrade manifests: one
for selected security-critical packages, one for the astronomy packages
so Sharlatan can save a bit on energy at home ;-), one for R packages,
and so on.

Another one I’d like to have: automatic ungrafting so that we could
apply ungrafting packages “anytime” (ideally!).

The sky’s the limit!
