Then don't worry about rare failures, unless there is a compelling reason to do so.
I guess I could EVENTUALLY take the changes I can see in the newer I2C library and incorporate them into the existing WIRE library, perhaps with a few compile time #ifDef's so I can easily select between them? Somehow I think that might be better than altering specific device libraries right? At least it should make me immune to breaking a project when one of those libraries is updated. The LCD library I'm using is pretty old.
