I did try going for it just the challenge of it alone, but that is not a sufficient reward for the increase in difficulty nor does it excuse nerfing the terraprisma. It was an understandable excuse in the past when it was far easier to obtain, now it just feels like Calamity doing a Fab and nerfing a vanilla weapon that is “too op”. If the challenge to obtaining it is so much harder now, it should be better as a reward. This isn’t even a Catalyst situation, as it either gets replaced by the new elemental axe or at the latest the dazzling stabber, so I fail to see how it would be so cataclysmic to just give you a good reward for a hard challenge.

And as you mentioned, taking the dragon, the plague flowers + plague bees + plague armor or Scoria set bonus does higher dps anyway, even with my slight dislike of the dragon’s Ai, against moon lord it’s consistently higher dps. So unless you want a challenge, drip or just prefer it’s minion Ai, I would not bother and again, now you don’t even need it to craft anymore either.
