From Chrome Apps to the Web
This is going to be really annoying since hardware access from HTML5 is still very rough and not even standardized.  Stuff like talking to a serial port isn't even on the radar (so good luck programming a board like BBC micro:bit, Arduino, etc. without a native app), and efforts like WebUSB are still extremely early and not even a full standard.  I feel like the product managers making this decision are completely oblivious to the major gaps between chrome app support & HTML5 support.  This line in particular is basically a giant middle finger to folks in this situation: "Developers who can’t fully move their apps to the web can help us prioritize new APIs to fill the gaps left by Chrome apps."So in short, Google proves once again to _never_ take a bet on their technology.
