If this package is called "readline" (with a new version number) most libraries i.e. like Shellac would not need modifications.
Well, we do have to take some care. This new package cannot depend on either of the two implementation packages. So when you upgrade, your programs will stop compiling until you manually install one of the two. People who are not aware of what is going on will be perplexed. Perhaps the upgrade path would be smoother if we end-of-life the readline package, and replace it with readline-iface plus the two implementation packages. The last version of readline would be emtpy, with dependencies on readline-iface and readline-readline, and a comment that it can be safely removed once installed. That is the strategy commonly used for this situation by other package systems, like Debian. What do you think? -Yitz
