Review Comment:
   > +1 to having it well documented so devs/committers are aware of what can 
be done or not.
   
   +1 -  we need some clear guideance / documentation. People need to know what 
to expect if they are using deprecated things. Judging from the cleanup 
process, we deprecated things (e.g. via a Javadoc comment) but never get down 
the road to actually cleanup or remove them ;-)
   
   > Sure. IMHO, it's important to define under which circumstances deprecation 
is tolerable, or in other words how to evolve an API. I've seen spots in the 
OpenNLP code where only a JavaDoc comment signals deprecation, so the compiler 
wouldn't warn devs (external or "homies").
   
   I am +1 with @mawiesne  - the best thing would be, that we find some consent 
on how to deal with deprecated things between releases and document it, so we 
have some written consent, which isn't forgotten or only in the "heads" :-)
   
   That said, I really appreciate @mawiesne effort to increase the readability 
& clarity of the code! :)
