Blackstar, what you're speaking of is what happens in the various agencies and conferences where the decadal studies are done. That's where all the long-term planning happens, and yes, of course there is a LOT of long-term planning done. I never said there wasn't. What I was talking about was the difficulty encountered when the approved proposals finally get into Congress to seek the required funding. That's where it gets difficult.  Many, many very good proposals have either died there or survived as a shell of their former selves. Some do make it thru, and you have named some of them. The people you are talking about are dedicated scientists that work their hearts out to create solid science missions that would be worth every dime they would cost, if only they could get funded. What I was talking about is what happens inside Congress when those proposals start the process of seeking funding. Apples and oranges.

@Salo put up a NASA proposal to do a Discovery class fast flyby mission to Triton in the US Launch Schedule thread. It involved using an EVEEJN trajectory with a nominal  Atlas V 401 launching in 2026 with 2038 arrival at Triton.

My thought on the proposed mission is that it should have a more capable launch vehicle option. Never mind that the Atlas V might be phased out by 2026.
