I poked around a bit. The 3.0.0-alpha2 binary tarball is only 246M and has
more changes than 2.8.0.

It looks like the 2.8.0 bin tarball has an extra 1.5GB of docs when
extracted compared to 3.0.0-alpha2. I think it's from the extra src-html
content:

-> % find share/doc -name src-html | xargs du -sb | awk -e '{SUM+=3D$1} END
{print SUM}'
