This is kind of a detail, but if we already assume methods which would allow for unbounded value in the absence of vacuum decay, it should not be certain that the presence of vacuum collapse creates a bound. I would expect that it basically creates a finite (expected) lifetime to any single causally connected bubble of the universe, but this could be counteracted by sufficient rates of inflation creating and disconnecting ever more bubbles at a higher rate.
This point aside, I had not realized that there actually are theoretical expectations for the Higgs ground state(s). I only learned about the toy models in my lectures and never looked up how they related to the full standard model. Thanks!
