First off, welcome to the forums!

Your question is a little bit misleading… For example, primitives and points don't have an ID attribute by default (only particles do). There is however, a point/primitve number each one gets.

Secondly, what happens if 200 points/primitives in your scene have a $CR > .1 ? Which point/primitive number do you want it to return?

Perhaps we can be of more help if you explain what this is for.

On a side note, there is a poppointid expression that might be of use to you if this is for particles.

Yup. It all works.
On a Mac Keyboard you have: Control - Option/Alt - Command/Apple.
On a Win Keyboard you have: Control - Windows - Alt

So, using a Mac Keyboard in Windows, the Control Button = Control. Option = Option. And Command/Apple = Windows key - which pops up the Windows Start Menu when pressed. I still slip on occasion and try to hit Cmnd-Shift-S to Save-As, only to have the Windows start-up menu pop up.

XCF Ladder Still works. Simply put, it all just works. OBJ, SOPS, COPS, ROPS, and POPs I've tested pretty thoroughly over the past few weeks with no hiccups. DOPS and VOPS I haven't tested too much – I don't know DOPs, and I've only made one very simple VOP shader and it worked, so it's probably safe to assume it all works. I don't see why it wouldn't.

Hope that helps. If you have any other questions let me know.

Minus the delete key, what would you want me to test?
