I assume (perhaps wrongly) you mean my post? Well, I posted as a separate topic because the mod I wanted was something really simple and straightforward. A mod that basically did nothing by itself. Great eh? As a result, the community has a new "tool" for custom packs.
If I posted here, it most likely wouldn't have got noticed among all the other great/crazy ideas. Since I've been on these forums quite some time and am known a little bit, I took a gamble with a separate topic. The last person I expected to respond was KL! True fact, before I posted, I search for other mods that could do what I wanted, looked at "mod maker" tools (gah!) and even considered trying to get a grasp on java but got an headache trying to understand "the basics".
TBH, very few posts in this topic really give enough information, or are for really complex ideas.
But, some people with modding skills do look at this topic, and the occasional mod is made, or ideas are used in bigger mods. Still post here though, as it can give ideas to modders, with a sense of flavour of what people are after.
Your idea you mentioned sounds a bit like Hardcore Questing mode, and could be a future feature, blocking crafting of block X until action Y is performed. Might be worth mentioning the idea on the MCF forums in that mods topic? It's a good one.
