the way I read the regs, it would be better to leave them installed if you can make sure they will not be actuated. But etap batteries come right off, there is one on each derailleur. And they are small enough that it would be wise to have spares on a 1200k. Di2 batteries are often buried in the frame.
The industry is moving away from rim brakes, the main thing I'm worried about is the availability of good rims. I think we're already seeing fewer rim brake rims. It's a lot easier to make a disc rim, doesn't really have to be straight. At least none of the rims I ever got from Stan's was anywhere near straight.
