openrsync is not a suitable replacement for standard use-cases of rsync.
It was specifically written for rpki-client and misses things that were
not needed for that.

Apple have a heavily modified version of openrsync which is closer to
being usable for standard cases, but it still has issues.

In particular all openrsync versions only support the old pre-2008 rsync
protocol version, which means that the full file list is transferred
before sending files; with a large set of files that is significantly
slower and takes many more resources on both sides than the incremental
file list in newer protocol versions.
