This is great to see, thanks for this work!

That would add 15 MB after removing 8 MB, so this would still be a net
loss of 7 MB; I don't think we can afford that, since we are still in
"desperate mode" on the CDs -- we removed almost all langpacks before
alpha-2, so we currently have almost no i18n support, and we already
had to do a lot of work to get alpha-3 non-overflown.

However, if we get enough space for -extra, I'd keep the split in any
case, since it's not needed for the majority of systems. So it should
still be possible to uninstall it on small footprint systems.
