Alex Petrov commented on CASSANDRA-17332:
-----------------------------------------

bq. I feel like for testing if the setting isn't cluster-wide, it's a sharp 
edge waiting to cut someone. 

I don't see anything strange about it at all, considering how this setting 
works right now. It's just a matter of how the node advertises itself, calling 
for token metadata updates across the cluster. When token metadata is 
transactional, this will be not only a normal, but also preferred scenario, 
since you'll be able to transfer tokens or ranges across the cluster in an 
arbitrary manner, so I don't see why we should limit ourselves to a specific 
number of tokens per node.

> Right now python dtests need to keep running after being ported to jvm-dtests 
> as vnode support is not present, to fully deprecate the python dtests, we 
> need vnode support in jvm-dtest.
> Sadly, to add support we need to break binary compatibility, but can maintain 
> source compatibility… so will need to bump every jar across every branch 
> (mostly due to TokenSupplier)
