I do understand your sentiment. To the public, derestricting is only ever going to cause negativity, it will never help the emtb cause. So in that respect it could be deemed a very selfish thing to do. Not to mention that if the s**t really does hit the fan and you kill/give someone lifelong injuries you are going to have a really bad day gripping the rail in court trying to explain that your derestricted emtb isn't an uninsured motorcycle.
On the other, derestricting for another 10kmh or so isn't going to be obvious to Joe Bloggs nor will it suddenly tear up the landscape like a 500cc crosser. But then I would have to ask, if 10kmh is all I am after, is it really worth bothering? I hear the comments above about it being enough to help clear a jump etc but as you say, maybe these riders need to put a bit more effort in or simply not attempt the gap jumps. Otherwise where will it end? Some gaps may need far more than 35kmh...so do we just keep upping our ebike derestriction speed until we can clear them under assistance only? Or do we simply say 'I'm not quick enough for these jumps', admit defeat and go out and buy an MX bike to do it properly. It does seem that some riders want a bicycle to have the ability and thrills of an MX bike but without the hassle/noise of owning/running an MX bike.
For myself, maybe the responsibility of having a house/kids etc and getting older scares me from getting lumped with the aforementioned rather remote but still possible court case which in reality could not only financially ruin me but also my family. For sure I was far less bothered in my teens..
I am in no way criticising owners of derestricted bikes (my old Bafang hub drive did 24mph) so I am not throwing stones, just throwing out some thoughts instead.
