Thing is, by the time you have to take back this application for maintenance, chances are high that the then mainstream framework will be outdated, newcomers won't even know it, the doc will have vanished in a poor "let's move to this new shiny TLD", and still the business logic of the application will be vastly undocumented as well.

I was on your side for a long time, but I've come to appreciate a minimalist, simple, well documented in-house framework over a hype-driven "solve-all-the-thing" one, even free and with a currently big community.
