Yes. There's a Japanese podcast (rebuild.fm) where one of the recurring guest (Hak) is from a game dev background and was probably assigned to Stadia. He never said it explicitely but from the conversation you would guess.
One of their discussion was on how much commitment was crucial in the game dev world. Devs on all sides (platform, libraries, actual game) would put their skin in the game and gamble time and money but also personal energy to make something successful, and there was an expectation that all participant would stick together even as the future gets bleaker (what comes to my mind is Nintendo supporting and pushing the Wii U for a while, even as it was a clear failure, or Sony keeping the Vita alive as much as they could)
Your reputation as a platform maker gets a serious hit if you're ready to quit the minute your forecast gets dark, and game devs never really forget this kind of things, unlike other more opportunistic ecosystems.
I kinda hope the Stadia team could move on outside of Google to a more fitting company..
