does this risk breaking support for ChromeOS Chrome on X11? 

I realize that we will get rid of that configuration eventually and be
ozone-everywhere but I didn't think that we were yet?

ChromeOS Chrome on X11 should still work just fine. Chrome is not running as a
system compositor in that case so you'd avoid passing the flag that makes this
return true in that case.
