My perspective is that it really isn't worth the risk, at least not right now. I did everything right (right browser, VPN connection, very discreet, used BTC), and I still had a visit from LE. I was also in Canada, which historically has been less aggressive than US LE on these kinds of questions.
I don't think D can do much at this point. LE has, somehow, recognized what is in the packages and has associated a source region with N, so any packages coming from D will likely get screened indefinitely. One issue I thought about endlessly while agonizing over what was going to happen (I am not in any actual trouble, btw, but I have been warned) was that there is currently a global N shortage and that D could (accidentally/unknowingly) ship K instead of N - the same company that manufactures their brand of N also produces very similar bottles of K, and even their names are almost identical. While importing N would, in most cases (hopefully) get you a slap on the wrist, you could do some serious jail time if you unknowingly possess K.
I don't know. I desperately want to CTB and I'm so, so, so jealous of people who have N, so I totally feel for people still pursuing this option. But I can tell you that those two weeks waiting for my package - and then getting visited by LE - were among the worst of my life. I have SN and will likely have to CTB with it, but I'd rather try with SN than risk being put in handcuffs and having absolutely no control left over my CTB.
