sorry for reviving this thread so late, but I only now gained more  
experience with
this package splitting.

Personally I don't like it too much. I partly understand the reason, but I  
am not
sure if this religious package naming makes sense.

As already mentioned in this thread, there is the issue of package  
Secondly, it is often no clear cut between spi/api/internal and lastly I  
it now much harder to have a mental picture of the structural organization  
the software. All I see in the package explorer are spis, apis and  

Don't get me wrong, some of the package changes are sensible, but should  
we force
this split on each single level?

An idea which came up was whether we couldn't use an annotation processor  
another one ;-). We could define custom annotations (@SPI, @PublicApi)  
which the
annotation processor could pick up on and create the correct META-INF or  
whatever is needed.
