But when one compresses a file with bzip2 and prepare a smaller
distribution, hundreds of people can save their download time. That's
why we compress things. I'd focus on the receivers' side.
Of course a necessary manner is preparing also a gzip'ed file for
those who prefer gzip's less memory usage rather than bzip2's higher
compression. And still, a standard is a standard.

Not everyone wants/needs to compress such a big stuff with bzip2
to waste time. But having bzip2/bunzip2 gives us an option.

Despite all of above, I have to agree that, since whether having bzip2
is already an option thanks to the port. :)
