FreeCAD is an open project, so you don't need permission to test and implement your ideas. You can just do it yourself. If it's a good idea it will catch on and become popular in a short time.
The FAQs were created precisely because some users took the initiative to write them. They were tired of answering the same questions over and over again, so they decided to find a solution to that. But no solution is perfect and it may need constant maintenance by interested parties.
So my advice is, don't wait for us, the FreeCAD community, to do something; if you think you can improve things, then do it yourself, and promote it. I've added and modified hundreds of pages in the wiki because I thought there was incomplete, incorrect, and outdated information, or information that could be explained in a better way. I don't know if this will be useful to somebody else beside me, but I still do it.
