You can do a lot of crazy crap if you practice hopping a little (e-bike or not). When it comes right down to it, though, on an actual ride I usually just walk (for 15 seconds) stuff I'd have to hop for 30 seconds to get up. It's not actually that fun after you get the skill figured out, and it takes a ton of effort/energy (probably even moreso on the e-bike, actually).
Bike trials can be fun in it's own right but it mostly is just dumb when it comes to trail riding unless cleaning tech uphill (Scott Trials!) is your thing. Same goes for doing manuals or any number of other impressive tricks - they are fun to be able to do, but they don't do anything much for you on a normal ride.
Check out some unicycle trials videos sometime. When terrain gets gnar enough, the unis actually are better than the bikes.
