Comment Layers?

I'm finishing up a skin and I was wondering if it's OK to include comment layers in the PSD? In other words, I really felt the need to organize my skin and mark the beginning of related layers by placing a completely empty layer above them and naming it with a comment about what follows.
So, as long as I don't include keywords in the comments, is this something that would not be a detriment to the functionality of the skin?
