Can you please clarify at least a little?

Will it be shorter for planned maintenance which doesn’t need to pay for failure detection but have to make sure no data is lost on failover?

Also availability number of such setup probably differs from standalone Galera cluster which you’ve mentioned as 99.995%. Any idea how this number changes for the described setup?
