I don't quite agree. There have been plenty of times mid-late game when I just didn't have enough curse detection/removing scrolls on hand to handle all the artefacts and such that I found, and where my ID scrolls were valuable enough that it prevented me from just wearing the things right away. I've had times where I've had to bring artefacts back to my stash to ID/wear later, because I couldn't spare scrolls.
Also, even if remove/detect curse is common, curses still prevent you from trying on every single item you find the instant you find it. Also, mummies.
How? Every time I walk into Vaults, I've got 10 spare ?oCD and ?oRC each in my stash plus probably another 2 or 3 of each in my inventory. It only gets worse with time. I've walked out of Elf:7 with 20 ?oCD and ?oRC each. That's AFTER using as many as I needed. I've ran out ?oID before, yes, but I'm not talking about that. I'm talking solely about curses in general.
I will accept that there's other ways to make curses relevant, but mummies and Ashenzari are not even close to enough. A 3-runer taking Okie or Nemelex will meet an absurdly small number of mummies and of course doesn't care about Ashenzari. So the only curses are items generated cursed and the 3 items that will be cursed by ?oCW, ?oCA, and ?oCJ. Of those curses, the ? based curses are irrelevant. The generated cursed items are only relevant if they post a danger, which basically means =oHunger and -stat stuff if it causes stat death. That's not a whole lot of cursed stuff. Anything else you can easily either head back to your stash to remove or wait til another ?oRC generates. Or if it's still the early game, then "oInaccuracy is relevant. Everything else, it's no big deal.
Once everything burns to ashes in the hell branches and you want to clear out the tomb, it becomes a rather larger issue.....
Why the fuck are you carring scrolls into Gehenna? Or any Hell, for that matter? Or here's a better idea, do Tomb first. And in any case, it only takes a single ?oRC to get rid of all the curses, so just walk into Tomb with your best equipment on and uncurse only when you leave.
