You'd have a slot per ABI, and be encouraged to allow multiple versions of glib to be installed in parallel. If you really couldn't do that (and you should think very carefully before saying you can't, since this directly affects users in a huge way), you can make the slots block each other. > - What would occur with packages forced to use eapi0 due backwards > compat?
