I have no idea if it is currently supported, planned for continuing support etc.
However, a quick google search yielded plenty of information about what it does. See for instance, the first hit I got: http://beeznest.wordpress.com/2005/02/03/rsyncable-gzip/ Suppose you have a file that you wish to compress and then synchronize between two computers using rsync. Then suppose you change the file (or even a single small file in a tar.gz archive) on the computer of origin and recompress. Without the --rsyncable option the entire new archive may well differ at the byte level all through it, forcing rsync to send an entirely new version to the remote computer. The --rsyncable option is supposed to change the behavior of gzip during compression such that rsync will be able to transmit just the changed portions (plus some minimal padding in the area of the archive that necessarily changed as a result of the changes in the file) when updating rather than having to send the entire compressed file all over again even when there is only a small change...
