Its actually a big change, as swiping up just opens the Google Maps bottom menu. The home row replaces gesture nav (which I can't stand...another UI feature they've been slowing pushing)
My current workaround is to trampoline off another program, like Spotify, or the BT settings, that has a constant notification then i can click that which opens the lock screen.
But even a small sounding change can be significant. After the last Gemini push, the alarm clock now would "stop" on voice command, but it would activate for random noises you made, cancelling my alarm for work; the settings were hidden in another app, not the alarm. It wasn't even promoted so nobody knew. This release mentions even more Gemini integrations...
