Hi André,

Yes.  I just tried ‘guix pull -s i686-linux’ for commit
e641d707e1ec8de2bfc658dcd1757360300aa509 and it passed!

This is certainly due to the reduced heap usage in Guile 3.0.8.
However, while building
/gnu/store/87mqnqwxqbcidbx5bpyrq9xpxmhw1035-guix-packages-base.drv we’re
still peaking at 2.6G resident—only 7% less than before (the packages
files have probably grown in the meantime), so we cannot claim victory
yet.

I think splitting the file would still be useful, yes; I don’t think
anyone is working on it.

Another thing to consider would be to balance things a bit better, by
arranging so that fewer modules are in ‘guix-packages-base’:

--8<---------------cut here---------------end--------------->8---

For the record, ‘guix-packages-base’ is computed in (guix self) as the
closure of (gnu packages base).

Thanks for your message!
