Hi,

Great to hear you're interested in working on this! I work at Oracle, 
and might be able to help with questions you have, though I don't have 
much in-depth knowledge of cluster.

Cluster's major versions are based on corresponding MySQL server 
versions: 7.2 for 5.5, 7.3 and 7.4 for 5.6, and 7.5 (currently rc) for 
5.7. There's no dependency on MySQL, as cluster is built from its own 
source, but there would be conflicts between the binary packages since 
cluster is built on top of MySQL.

Besides that, the main difference would be that actually setting up 
cluster to use is significantly more complicated than the basic server.
