It should work fine with num_tokens: 1
Without vnodes it also flushes to per-range sstables (if you have RF=3 you
will "always" get 3 sstables after flush), while with vnodes it groups the
ranges and flushes a full disk, so if you have a single
data_file_directories you get only one sstable, then
I've had similar thoughts in the past about RACS and manual tokens. I think
it would be a good idea to be able to split it based on some configurable
factor other than vnodes. I think Marcus may have already addressed this to
some extent as well but if not it's theoretically possible.

I don't want to comment on the 10540 ticket since it seems very well
focused on vnode-aligned sstable partitioning and compaction. I'm pretty
excited about that ticket. RACS should enable:
- smaller scale LCS, more constrained I/O consumption
- less sstables to hit in read path
