What history? When did the Fed ever lower rates because of the deficit?
> Japan where BoJ effectively owns almost all of the Japanese government debt.
Help me understand why a large holder of debt would want it to pay less? (Also, Japan is a bad model for America.)
> not naive enough to believe into the soft and no-landing scenarios
That's fine. That's reasonable. What's not is thinking we'll have deficits cause lower rates and then inflation. If we have a hard landing, which is the historically-suggested outcome, we get lower rates and a recession. Not inflation.
> it becomes another form of QE.
No, because new money isn't being created. Existing money is not being removed. That's different.

How?
> If you set the penalty rate on the level of the current Fed rate
It already is. This is how it works.
> since they can give enough loans at such rates and deposits actively flee into treasures and MMFs
How does the discount rate cause deposits to flee?
Also, what?! The discount rate is 5.5% [1]. Banks can borrow against the market value of their Treasuries at that. So for a dollar of face value, they can borrow ~60¢ at 5.5%. If we penalty that for face-value borrowing, they can borrow 100¢ at e.g. 8.5%. Help me understand how this additional liquidity causes whatever you're predicting?
