So someone changing the behavior of an analyzer should fallback to the previous behavior if an old version number is passed.
What I fear with this approach is that: - you cannot see at compile time which analyzer has changed and which one has not (which is what people are interested in in the first place) - this model does not work for third party analyzers unless you multiply the number of version dependencies and then it becomes utterly confusing. - it increases the complexity matrix. A user has to provide the Lucene version + the passed version for each analyzer (and affiliated) used Java 7 and Jigsaw could solve some of those problems (though not all). At the end of the day, I wonder if this will not create more issues than the ones it is preventing. I hope I'm wrong.
