No, sadly, that stuff is too easily ignored in the age of component pouches and other spell foci. They are the next item on my list to get chucked, but I'll need to think about the ramifications for a little while yet.
I also like the nut shells for Confusion. But we dont use really use components - they dont feel magical to us - so it doesn't come up in play, even though it is fun to seem them in a read through.
