What makes you think it did not keep going?  When using --keep-going
you’ll still get an error at the end if one or more builds failed.

This is simply because commit 572ee05c3134cf9408ba463c97fdbacb9a98f714
dates back to 2016 at a time where ‘guix pull’ and related files where
not “future-proof”, so we just cannot roll back this far I’m afraid.

Again the changes to ‘guix pull’ made shortly before 0.15 should fix the
issue and allow us to go back further in future history, if you see what
I mean.  :-)
