But it seems that that's exactly what rsync does:
It performs bulk data writes without reading. There are 32 kB in the
receive buffers, and rsync continues to write. If the process would read
some data the TCP stack would immediately recover.

RST are already processed, ACK's should be processed, but what about
URG?
