Opinions on Rules Cyclopedia's Treatment of Thieves Skills?

The RC has some interesting takes on Thieves Skills that I don't think I've seen in other classic D&D books.

For Find Traps, it outright says that this is for room and object traps, and that no one else has a chance to attempt this. It seems it's more popular in the OSR these days to open up trap finding for everyone or to treat Find Traps more like a saving throw for Thieves.

For Remove Traps, it opens it up to removing or deactivating any trap, with a failed roll directly triggering it. It's interesting how in the Greyhawk supplement, it specifically stated that remove traps was just for tiny treasure traps, yet when you flash forward to the RC, it's for any trap, really.

The rules for Hide in Shadows in the RC seem kind of odd to me; you first roll to successfully Hide in Shadows, and if someone looks directly at you while you're hiding, you have to make that roll again or be caught. It's already a low chance of successs, and it seems kind of hard to adjudicate if someone is looking "directly" at the Thief or not.

For Move Silently, it's not radical or anything (% roll to succeed or fail).

What are your opinions on these ways of handling Thieves Skills? These seem a bit more punitive and restrictive than other Original/Basic rulesets. I think it's interesting to see how the modern OSR way of handling these things contrasts with the actual old-school rules.
