In the end those few situations could be package maintainer for Linux
distributions or alternative package managers like brew for OSX in need
of verifying the Boost release they got for their thousands of users.

For example, here's how brew does it currently:

And although there is a SHA256 checksum in there, it probably comes from
the initial developer downloading the Boost release and calculating the
checksum locally, as there are no checksums I could find from the Boost
Release Team.

Therefore all it does is verifying file integrity _for the file that
Sourceforge hosts_.
