> One perhaps minor comment about the codec reader gate is that the reading side already supports reading from N-2 fully. I am not sure this distinction was made above. Lucene 10 reads indices created in Lucene 8.0 and onwards. That is possible via an expert `DirectoryReader#open` method that takes a min supported major argument (see [c1ae6dc](https://github.com/apache/lucene/commit/c1ae6dc07c9a988533cbe7176bdeb49e2fca1d9c)). 8.0 codecs are still shipped with Lucene 10, hence no change is really needed there. We may decide to leave 8.0 codecs around in Lucene 11 as well if we want to ship it soon? The only thing we'll need to do is indeed flip the min supported major constant so that reading from N-2 (or -3?) does not require a separate API call. I hate this too. We all carry the burden of extra back compat, but it doesn't work for ordinary users, only big companies who know how to hold the expert API. -- This is an automated message from the Apache Git Service.
