I can agree with pretty much all sides of this. As this is in Showcase and is Smoot's baby, he's free to entertain and reject all ideas of what should and shouldn't be in the LM. I can understand this or any magic-related supplement not making it to print. I think the same problem/difficulties arise for those who keep asking for an advanced game/supplement.
For those who want to contribute more 0-level spells and/or new spells, there are documents on the Downloads page for those, and we certainly welcome more ideas, feedback, etc. in those threads. If those are added to or changed, it would be up to Smoot whether to update the LM as well.
