Many people over the years have suggested something like this. The hardest part is actually coming up with the content: writing decent docs, especially comparisons, is time-consuming and hard.

There's no point in having lots of infrastructure if there won't be the content to go in it.

Or to put it another way round: your suggestion seems to be a solution to the problem of us having too many decent guides and comparisons but nowhere to put them. I don't believe that's currently a problem we have.
