Too Much Security?

Besides for the delay tactics which I feel like I can ignore, I don't really care or think it is a big deal in which room the court presides to hear the testimony of PM Benjamin Netanyahu.
That being said, I am still curious about the claim that was made when requesting the change of venue. 
PM Netanyahu submitted the request to change the location of the court hearing to an underground secure location due to security concerns with the ongoing war. Ever since the drone from Hezbollah that hit his house in Ceasaria he has been super paranoid about his personal security, despite being the most secured person in the country. But that is understandable.
My curiosity is that while it sort of made reasonable sense before, even when the request was submitted, now it seems unnecessary. Since the request was submitted Netanyahu signed a ceasefire arrangement with Hezbollah/Lebanon, and, so far, it seems to be holding. Hamas has been rendered impotent and has not been able to fire rockets in a while, let alone rockets that can reach deep into the country.
What is the threat now that he is worried about that requires special accommodations for securing the hall to be used for the court session beyond what the normally top level security he would be getting anyway as the presence of the Prime Minister?
Is it just another attempt to delay the session as he is hoping they will have difficulty securing it properly and will have to delay again for security considerations or is there a real security concern of some sort beyond what his daily protection can secure?
While perhaps you can never have enough security, I remember he used to scoff at Nasrallah for hiding in the tunnels like a rat and never coming out, but he too barely comes out - even his recent Channel 14 interview was pre-recorded in the "Pit" of the Kirya, he's moved some government meetings to undisclosed secure locations, and this court session has to be underground, etc... what is he so afraid of?
