There isn't a GECK (or whatever they'll call it for FO4), no FO4Edit, and Snip is breaking things just like it did for Skyrim. Plus, as Toast said, there's no official patch release yet. All the tools that the Skyrim modding scene has now just aren't there for FO4 yet.
And plus, there's a standard that needs to be met. In some "community patches" for FO3 and FONV, very subjective changes were made to gameplay mechanics, ones that had only the most spurious rationale for being bugs. The Unofficial Patch Project team for Oblivion and Skyrim aren't perfect, but the standard we follow is much more stringent for what is and is not a bug. A lot of consideration also needs to be put into how to fix a bug without breaking other things; each BGS game gets more and more complex than the previous, and things can cascade if one is not careful.
Supporting this theoretical UF4P would no small undertaking either; even with the recent USLEEP unification simplifying things into maintaining just one patch module, we still have our arms full with people not understanding that "Exists with USLEEP active, fixed with USLEEP not active" is not definitive proof that USLEEP is the culprit of whatever bug, or that the lack of anyone else reporting whatever showstopper they have means it's unique to their mod load.
