Looks like they are trying to make it worth with a1111.

  Here are a few things we’d be excited to support…
   Local inference through WebGPU
   Local inference through stable-diffusion-webui
   Desktop installation
   ControlNet tools

I wouldn't bet on it. Automatic1111 already has a strong community and growing ecosystem. Stability.ai would have to try really hard and offer something significant to win people over.

Very curious to this as well, I’d imagine not unless something dramatic happens as Automatic is the gathering storm of public support and interest.
