Jonathan Ellis commented on CASSANDRA-2920:
-------------------------------------------

It could, but the point of this ticket is that a rolling upgrade from 0.8.x to 
1.0 will hit this:

{code}
        if (!desc.isLatestVersion)
            // TODO: streaming between different versions will fail: need 
support for
            // recovering other versions to provide a stable streaming api
            throw new RuntimeException(String.format("Cannot recover SSTable %s 
due to version mismatch. (current version is %s).", desc.toString()
                                                     , 
Descriptor.CURRENT_VERSION));
{code}

So it doesn't matter whether we support it at the streaming protocol level or 
not.

> CASSANDRA-2677 left Builder-oriented streaming in for backwards 
> compatibility, but since we're going to change the sstable format for 1.0, 
> and Builder doesn't work across format changes, there's no point in leaving 
> Builder around.
