Right. It seems to me that not having the ABI flags for packages like x11-proto/* would make more sense, but may be more work to implement. > Those ABI flags behave the same as other USE flags: When you change > them, you have to recompile the package including all the content, that > has been compiled previously. > If you want the compile for each ABI seperate, then you would have to > handle them more like SLOTS, but with a new syntax, with a collision > handler for the common content and how to handle that in the user UI.

I already think a mechanism for telling the package manager "you don't need to rebuild this entire package to turn on /this/ USE flag" is needed. For ABIs, the situation seems much more clear-cut. In fact, it seems rather important.
