You're forgetting something: This will not work for iOS. Why develop something which excludes a big chunk of the cake? I'm happy Google is not going this way... Apple is doing already enough damage with exclusive features.

By that logic nobody should even create native Android apps today. You're saying that if Android apps could run on even more platforms it would somehow stop being worth it to create them because iOS is excluded? Makes absolutely zero sense.
I would also go even further and would say it makes in MOST cases no sense to develop a purely native app today. From a economic standpoint most native, one platform apps make no sense nowadays (also many people are unwilling to install more apps) unless you have deep enough pockets. I'm happy that Chrome embraces the web and pushes web application even further. I see really no benefit in running Android apps on my Mac (this results in mixed touchscreen, non touchscreen experience). So Chrome is pushing technology for this 80-90% of devices but it is not Android (with its touchscreen focus) and I'm really happy it is the web which I can use on more devices with different UX handling and without installing stuff.
