I'm starting to think about your point re. parts availability and am going to keep my eye out for an Ultegra 6870 front derailleur on sale or maybe used to keep around as a spare.
I plan on replacing the ULtegra 6870 rear derailleur on my bike with one of the new Ultegra R8050 Shadow derailleurs in a few months and the existing RD6870 will become the spare.
Not worried about levers just yet. Dura Ace 9xxx and Ultegra 8xxx hydraulic Di2 levers will be around for a while.
