One WAR with everything, one empty WAR and/or one WAR per database?

Hi, With the 1.1M3 release we have currently only released a hsql version of the platform WAR. That war only includes the HSQL JAR but not the driver JARS for other DBs. In our current build we can generate the platform WAR for other DBs using for ex: mvn install -Pmysql. That includes the driver JAR for that DB. Before we were bundling all driver JARs into our WAR so our users may be a bit confused and we need to decide on the strategy we want to have. I can see 3 possible strategies: 1) 1 WAR per database - We could start by releasing only 2 WARs: one for HSQL and one for MySQL. I don't think we need more and releasing more is going to be a pain as each WAR weights 40MB. 2) 1 WAR with everything - Cons: having all these DB drivers makes our WAR fatter - Possible solution: we only release the HSQL and MySQL drivers 3) 1 empty WAR I feel 3) might actually be the best solution for the following reasons: - if the user is non technical he'll install the standalone version - if the user is technical it means he shouldn't have any problem following install instructions that tell him to download such driver at such location and put it in WEB-INF/lib - we only release one common WAR and our XWiki Platform is environment independent (which is a new property to have I think) - releasing one WAR makes our release process simpler (only 40MB to release once) WDYT?
