A good reason for applications to only use formal versions (vs. trunk) is backwards compatibility (see "BackwardsCompatibility" in Lucene Wiki).
An index created with a formal version (major or minor), would be readable (and hence upgradable) by a later version. But for interim trunk states this is not guaranteed. For example, version 2.2 will correctly open a 2.1 index, but it might fail to open an index created with (say) the current trunk (in between 2.1 and 2.2).
