I don't know why the exp in jwk needs to be changed. From a developer POW there is no need. You always know which "exp" is the right one. I would reverse the change from exp to xpo. Developers don't need it and many did not update their implementation to incorporate the exp->xpo transition.
Actually I don't care (much) how the parameters are named. Although I would like to stick to the 3-letter scheme I am OK with the n,e proposal. But please stop making breaking changes (especially renaming parameters which leads only to more work and no gain). Case1: harm is already done -> stick with xpo and don't change AGAIN. Case2: Most implementation haven't changed yet -> revert to exp Case3: xpo is just stupid -> n,e is better -> another change -> Oh no -> revert to exp Again: I suggest to revert to exp and make the implementers happy. Axel Cc'ing Nat because I don't want to give away his developer's emails without asking.
