Well, I'm skeptical to this:
1. It requires Chrome 37+. Building Chromium ~20 required a lot of new(er) libraries, I think it might be impossible to build Chromium 37+ for Maemo
2. It uses amd64 binaries. _platform_specific directory is full of them.
3. Performance. Remember prewebenv? It was sluggish in Easy Debian, not much better natively.

I'm all for a chroot solution. If anyone decides to try it, I'm eager to contribute if someone undertakes creating "Easy Android" for Maemo.
