Note that you will still need all those pieces: *The database name and wiki prefix. *Server and port is desirable, since it may not always be on the same database server as the wiki (in which case we could reuse the same slave list). *The server is mysql. Probably uncommon to have several wikis communicated directly, on different kind of servers, but someone will take use of it, and it'll be easy to add.
On a $wgConf setup like WMF's, which is what we're aiming at, all this data is stored in $wgConf and the wiki ID can be fed into some LoadBalancer function (don't remember its name offhand) to get a DB connection. So you just need the wiki ID on these setups.
