I'm hoping there is a happy medium somewhere, such as rename the new parts so they can co exist or mark the original ones as obsolete (which there is a directory of) so old sketches will get the old parts unless updated but new sketches will get the new ones. I expect this has happened before and someone probably has a solution that works, because I'd like to see the parts work better without breaking all the old sketches or forcing an update if you don't want to make one.
