How to say this short: when testing the latest syncrep patches I've 
wasted time looking where the recv|fsync|apply api was, to find out it 
was gone. *shrug* didn't need it for my use case. But for others it 
might well be frustration to find out that what's currently called 
syncrep cannot be configured in a way it's suitable, and that they might 
have wasted considerable time while finding that out.

The dba interface for recv|fsync|apply seems to be pretty stable, so 
supporting that for years should be without risk. How it works under the 
hood - the beta period seems like *the* opportunity to attrach mayor 
testing from all people waiting to get their hands on syncrep.

An aspect of a good product is that it doesn't waste users time, like a 
good piece of code needs little comment. Alarm bells should go off when 
somebody is about to write a large piece of documentation writing what a 
feature doesn't support. It would be better to just support it 
(recv|fsync|apply), or no syncrep at all. Syncrep is incomplete without it.
