You shouldn't need to use the old syntax, as long as you use the API 
200. With API 201, the server is called with the new syntax 
(rdiff-backup server ...), else (the default) it's called with the old 
syntax (rdiff-backup --server ...). If you observed something different, 
please create an issue. In any case, you can still put whatever you want 
in the remote schema.

And, yes, at some point in time, I'll remove all the old code and I'll 
be happy about it. It'll be called v3.0.0. Before that there will be a 
few more 2.x versions (no promise how many), API 201 will become the 
default, API 202+ might be introduced, etc... So still a few more steps 
to take before this happens.

And, with 2.1x, you have the placeholder Vx/Vy/Vz you can use in your 
remote schema so that you can point at a dedicated version of 
rdiff-backup without fear of incompatibility. The man-page explains it all.

So, yes, there is always a balance between new features, avoidance of 
technical debt, and stability of the interface(s), which isn't easy to 
get. I'm doing my best but appreciate feedback.

Hope this helps, thanks for testing,
Eric
