The point of my statement is that it perfectly acceptable to change behavior in HEAD in a non-backwards compatible way. In particular no systems running -CURRENT are expected to be "critical functioning". People that track -HEAD are expected to be able to deal with the sorts of problems that occur from "drastic change." > But introducing known breakage is simply not acceptable.
