Michael McCandless commented on LUCENE-2076:
--------------------------------------------

bq. If Java Lucene does the same, can this be done for 3.0?

The problem is, we're trying hard to avoid new deprecations in 3.0.  2.9 was 
our chance to do deprecations.  Can we do this for 3.1 instead?

> On the Apache Lucene.Net side, we have done some clean up with the upcoming 
> 2.9.1 such that we are now depreciating improperly use of parameter type for 
> some public APIs.  When we release 3.0, those depreciated code will be 
> removed.
> One area where we had difficulty with required us to add a new method like 
> so: Lucene.Net.Store.FSDirectory.GetDirectory().  This method does the same 
> thing as Lucene.Net.Store.FSDirectory.GetFile().  This was necessary because 
> we switched over from using System.IO.FileInfo to System.IO.DirectoryInfo.  
> Why?  In the .NET world, a file and a directory are two different things.
> Why did we have to add Lucene.Net.Store.FSDirectory.GetDirectory()?  Because 
> we can't change the return type of Lucene.Net.Store.FSDirectory.GetFile() and 
> still remain backward compatible (API wise) to be depreciated with the next 
> release.
> Why ask for Java Lucene to add 
> org.apache.lucene.store.FSDirectory.getDirectory()?  To keep the APIs 1-to-1 
> in par with Java Lucene and Lucene.Net.
